The Altecnic / Caleffi 309 Pressure & Temperature Relief Valve - 309473CST is designed to effectively control and limit the temperature and pressure of hot water in domestic storage heaters. This essential safety device prevents water temperatures from exceeding 100°C, thereby eliminating the risk of steam formation. When the system reaches predetermined pressure or temperature thresholds, the valve discharges a sufficient amount of water into the atmosphere, ensuring that both temperature and pressure are maintained within safe operating limits. The valve's mechanism operates as follows: - **Temperature Control:** As the temperature in the storage heater rises, the thermostat compound within the temperature sensor, which is submerged in hot water, expands. This expansion causes a thrust pin to move, actuating the obturator and opening the valve. The valve is set to activate at temperatures exceeding 90°C. - **Pressure Control:** When pressure limits are reached, the obturator, which is opposed by a set spring, lifts and fully opens the outlet. The pressure setting is specifically configured according to the maximum allowable pressure within the system. As temperature and pressure subside, the valve automatically re-closes within designated tolerances.

The Altecnic / Caleffi 309 Pressure & Temperature Relief Valve - 309400CST is designed to effectively control and limit the temperature and pressure of hot water in domestic storage heaters. This essential safety valve ensures that water temperatures do not exceed 100°C, preventing steam formation. When the temperature or pressure reaches its set limits, the valve releases a sufficient amount of water into the atmosphere, ensuring that both temperature and pressure return to safe operating levels.

**How It Works:**

The valve features a thermostat compound within the temperature sensor that is submerged in the hot water storage heater. As the temperature increases, the compound expands, moving a thrust pin that activates the obturator, thereby opening the valve. This mechanism is set to initiate opening at temperatures exceeding 90°C. Regarding pressure, the obturator, which is countered by a spring, lifts when the pressure reaches its designated limit, fully opening the outlet. The pressure setting is predetermined based on the system's maximum permissible pressure. As the temperature and pressure decrease, the valve automatically re-closes within the specified tolerances.

The Reliance Water Controls (RWC) TPR15 Pressure and Temperature Relief Valves are compact yet robust solutions, expertly designed to safeguard against over-pressurisation in unvented hot water systems. These essential valves are specifically intended for installation at the upper section of a hot water cylinder, where the highest temperatures are typically encountered. In the event that the system temperature exceeds 95°C, the wax mixture within the temperature probe's element expands, lifting the valve off its seat to release water safely, thereby alleviating pressure within the cylinder. Furthermore, if water pressure escalates without a corresponding temperature rise, the valve remains shut until the predefined pressure of the relief mechanism is reached, at which point it will open to release excess pressure. Certain models feature a PTFE coating on the Male BSP inlet thread, facilitating a quicker and more efficient installation process. 

Features and Benefits:

• Provides protection against temperatures exceeding 95°C
• Prevents over-pressurisation of the system
• Twist top cartridge design for straightforward servicing
• Available with various pressure settings and probe lengths
• Includes PTFE coating in select models

Specifications:

• Size: 1/2" x 15mm
• Connections: BSP Male Inlet x Compression Outlet
• Materials: Brass
• Medium: Hot water only
• Set Pressure (Set & Locked): 7 Barg
• Temperature Relief: +90 to 95°C

The Reliance Water Controls (RWC) TPR15 Pressure & Temperature Relief Valves are compact, yet highly effective, valves designed specifically to protect your unvented hot water system from the dangers of over-pressurisation. This critical safety feature is essential, as over-pressurisation can occur if the input temperature or pressure controls fail. The valves are strategically designed to be installed at the top of a hot water cylinder, where the highest temperatures are typically found. Should the temperature exceed 95°C, the wax mixture in the temperature probe's element will expand, lifting the valve from its seat and allowing excess water to be discharged safely. Additionally, if water pressure increases without a corresponding temperature rise, the valve remains closed until the pre-set pressure of the relief mechanism is reached, at which point it opens to relieve the excess pressure. Some models are equipped with a PTFE coating on the MBSP inlet thread, facilitating a quicker and more efficient installation process.

Features and Benefits:

• Protects against temperatures exceeding 95°C
• Prevents over-pressurisation in hot water systems
• Innovative twist-top cartridge design for straightforward servicing
• Variety of pressure settings and probe lengths available
• Some models feature a PTFE coating for easy installation

Resideo Braukmann SV300 Pilot Operated Safety Valve

The Resideo Braukmann SV300 Pilot Operated Safety Valve is expertly engineered to manage the medium flowing through it via an integrated pilot valve. This valve is ideally suited for installation in supply pipework branches, providing crucial protection for downstream components that could be compromised by excessive pressure, often arising from pump activities. When the inlet pressure reaches the pre-set opening pressure, the valve promptly transitions to the maximum flow position. Conversely, if the pressure decreases to the designated level, the valve gradually closes to mitigate pressure shock loads.

We offer pilot-operated safety valves from renowned manufacturers. Please reach out to us with your specific requirements.

A pilot-operated safety valve (POSV) is a specialised pressure relief valve that utilises system pressure, through a smaller auxiliary valve known as the pilot, to regulate the opening and closing of the main valve. These valves are predominantly used in systems where precise pressure control and effective sealing are essential, especially under high-pressure conditions.

How It Works:

• The pilot valve continuously monitors system pressure and manages the main valve's operation.
• When pressure remains within safe limits, the pilot valve keeps the main valve closed by maintaining pressure on the upper side of the valve piston or diaphragm.
• If the pressure surpasses the predetermined limit, the pilot valve opens, allowing pressure to vent from above the piston, resulting in the main valve fully opening to relieve the pressure.
• Once the system pressure falls below the set point (considering hysteresis), the pilot valve closes, re-establishing pressure above the piston and shutting the main valve.

Advantages:

• Provides tight shutoff even close to the set pressure.
• Offers higher capacity and reduced leakage compared to direct spring-loaded valves.
• Features adjustable blow-down, which is the difference between the opening and closing pressure.
• More compact design suitable for high-pressure applications.

Disadvantages:

• Significantly more expensive than standard safety valves.

The Medenus SL10 Gas Safety Valve, featuring a spring-loaded design, is expertly engineered to mitigate short-term pressure surges in gas consumption systems. It effectively prevents unacceptably high pressure increases due to gas leaks, safeguarding downstream components from excessive pressure levels. This safety relief valve consists of an actuator housing and a functional unit known as the “control device.” In its closed position, gas flows into the actuator housing as indicated by the directional arrow. The internal measurement line port directs the outlet pressure to be regulated to the base of the main diaphragm within the safety relief valve. This system compares the actual pressure with the target value predetermined by the set point spring. The desired set point can be adjusted using the setting screw. When the pressure exceeds the set point, the measuring unit raises the actuator, allowing excess gas to escape through the blow-off line. Conversely, if the pressure drops below the set point, the measuring unit automatically closes the actuator.
