Berluto DRV378SW Seawater Reducing Valve

The Reliance Valves Aquasystem Stainless Steel Expansion Vessel is specifically designed for heating applications. Available in capacities ranging from 2 litres to 5000 litres, these vessels operate under maximum pressure ratings of 8.0 to 10.0 bars. Engineered with replaceable membranes, the Aquasystem series allows for in-situ servicing, which prevents water from coming into contact with the internal steel shell. This feature significantly reduces the risk of internal corrosion and extends the overall lifespan of the vessel.

Features and Benefits:

• Durable stainless steel bolted flange to prevent corrosion.
• Generously wide membrane opening to minimise noise caused by restricted flow.
• Internal membrane design that prevents water contact with the steel shell, inhibiting internal corrosion.
• Comprehensive capacity range from 2 to 5000 litres, suitable for all heating applications.
• All models come with a replaceable membrane, allowing maintenance without the need to remove the vessel.
• Includes a pre-charge valve for easy air pressure adjustments.
• Specifically designed for heating applications only.

The Medenus RS254 Gas Pressure Regulator and Shut Off Valve guarantees a consistent outlet pressure, irrespective of fluctuations in the primary inlet pressure. It efficiently adapts to variable gas consumption, providing rapid pressure regulation during sudden changes in flow rate. The integrated safety shut-off valve ensures secure operation by instantly shutting off the flow in cases of excessively high or low pressure.

The Medenus RS254 Gas Pressure Regulator and Shut Off Valve complies with the DVGW Code of Practice G260/262 and is suitable for all neutral and non-corrosive gases, with additional options available upon request. This versatile regulator is offered with flange connections from DN25 to DN200 and supports working pressures up to 16 bar. All Medenus gas pressure regulators are certified by DVGW and CE, ensuring the highest standards of safety and reliability.

The RS-series regulators boast a variety of options, including safety membranes, vent valves, remote release for the shut-off valve, noise reduction features, and many more. For detailed information, please refer to our documentation or get in touch with our team.

The Reliance Water Controls (RWC) TPR28 Pressure and Temperature Relief Valve is designed to safely discharge water, effectively preventing damage to hot water cylinders caused by excess pressure or high temperatures. These high-capacity valves are essential for both domestic and commercial applications, ensuring protection against over-pressurisation and temperatures exceeding 95°C. Such conditions can arise in unvented hot water systems if input temperature or pressure controls fail. The TPR28 Valve is specifically designed for installation at the upper section of a hot water cylinder, where the water reaches its highest temperatures. When activated, the valve lifts off its seat, allowing water to be released safely, thereby reducing both pressure and temperature within the cylinder.

**Features and Benefits:**

• High-capacity protection suitable for both domestic and commercial use.
• Prevents water temperatures from exceeding 95°C.
• Safeguards against over-pressurisation for enhanced safety.
• Equipped with a lever-style easing mechanism for ease of use.
• Available in various connection sizes to meet different system requirements.

**Specifications:**

• Size: 1" x 28mm
• Connections: BSP Male Inlet x Compression Outlet
• Materials: Brass
• Medium: Hot water only
• Set Pressure (Set & Locked): 7 Barg
• Temperature Relief: +90 to 95 degrees C
• Discharge Capacity: 50kW
• Probe Length: 195mm
• Product Code: PTEM100050
