CONCOA 332 Series Regulator

The Reliance Water Controls (RWC) TPR22 Pressure and Temperature Relief Valves are compact devices specifically engineered to safeguard unvented hot water systems against the risks of over-pressurisation. This risk arises when the input temperature or pressure controls fail. The valves are designed to be installed at the upper section of a hot water cylinder, where the highest temperatures are present. If the system temperature exceeds 95°C, the wax mixture within the temperature probe expands, lifting the valve off its seat to release water, thereby alleviating the pressure within the cylinder. Furthermore, should the water pressure rise (without a corresponding temperature increase), the valve remains closed until the preset pressure limit is achieved, at which point it opens to relieve the excess pressure. Certain models are equipped with a PTFE coating on the MBSP inlet thread, streamlining the installation process significantly.

Features and Benefits:

• Protects against temperatures exceeding 95°C
• Prevents over-pressurisation
• Twist top cartridge design for straightforward servicing

Ensure your hot water system remains safe and efficient with the RWC TPR22 Pressure and Temperature Relief Valves.

The PREL107010 Potable Water Pressure Relief Valve is designed to safely discharge water from the system when cold water over-pressurisation occurs in an unvented cylinder. The Reliance Valves 107 Series Potable Water Pressure Relief Valve offers essential protection for unvented systems against the dangers of over-pressurisation. Each valve is pre-set and locked to a specific pressure; if the system's pressure surpasses this threshold, the valve will lift off its seat, allowing water to be discharged safely to waste. This makes it the primary safety device in an unvented system. The valves are available in pressure settings from 3.5 to 6 bar, along with various connection sizes to accommodate different installation requirements.

Features and Benefits:

• Diaphragm design enhances resistance to scale build-up
• Provides reliable protection against over-pressurisation
• Various connection options allow for flexible installation
• Set relief pressure range between 3.5 and 6.0 bar
• Designed exclusively for cold water applications

Specifications:

• Size: 1/2" x 1/2"
• Connections: BSP Female Inlet x BSP Female Outlet
• Materials: Hot pressed DZR Brass
• Medium: Water
• Set Pressure: 6 Barg
• Temperature: Up to +110°C
• Product Code: PREL107010
• Notes: WRAS approved

Invest in the PREL107010 Potable Water Pressure Relief Valve for an efficient, reliable solution to safeguard your unvented system from the risks of over-pressurisation.

The NABIC 542 spares kit contains a new diaphragm and 'O' rings which replaces all of the soft goods in the valve. The kit is suitable for all of the valves based around the NABIC 542 valve body i.e. NABIC 542F, NABIC 542L.
