Storm Valve

The PREL101013 Reliance Water Controls (RWC) 101 Series Sealed Heating System Pressure Relief Valve is designed to safely discharge water from the system when a predetermined pressure is exceeded, providing essential protection against over-pressurisation in heating systems. The Reliance Valves 101 Series are widely utilised as a vital safety feature in sealed heating systems. Upon installation, the pressure relief valve is calibrated to the appropriate settings. When the system pressure elevates to this set limit, the valve activates, releasing water into the atmosphere to safeguard the system from reaching hazardous pressure levels that could potentially cause damage and present risks to individuals nearby.

**Features and Benefits:**

• The diaphragm design enhances resistance to scaling, thereby prolonging the lifespan of the valve.
• Easy removal of the single-piece cartridge allows convenient access for cleaning or replacing the cartridge.
• Flexible set relief pressure range from 2.0 bar to 6.0 bar aligns with diverse system design requirements.
• Available with FSBP or MBSP/FBSP connections, offering complete installation versatility.
• Designed exclusively for heating applications.

**Specifications:**

• Size: 3/4" x 3/4"
• Connections: BSP Female Inlet x BSP Female Outlet
• Materials: Hot pressed DZR Brass
• Medium: Water
• Set Pressure: 3 Barg
• Temperature: +140°C
• Product Code: PREL101013
• Notes: WRAS approved

This pressure relief valve is an essential component for ensuring the safety and efficiency of sealed heating systems. Invest in the PREL101013 Reliance Water Controls 101 Series for reliable performance and peace of mind.

This valve features a robust stainless steel ball and stem, complemented by P.T.F.E. seats and P.T.F.E. / FKM (Viton) seals. Engineered to flanged (wafer pattern) standards, it is compatible with PN16 flanges and operates via a user-friendly lever mechanism. Paired with a Valbia 82 series pneumatic actuator, this valve is ideally sized for a minimum pilot air supply pressure of 5.5 Bar g. Its innovative rack and pinion design, crafted from hard anodised aluminium, ensures durability. The blue-coated end caps offer additional protection, while the visual position indicator makes operation straightforward. Pneumatic connections are facilitated through 1/8” BSP fittings, and the actuator includes bi-directional open/close travel stops. It operates effectively under a maximum air supply pressure of 8 Bar g and bears an ATEX II 2GD T6 certification for safety. A mounting kit is also included, with the entire assembly rigorously tested for functionality. **Specifications** - **Size Range:** ½” to 6” - **End Connections:** Available in PN16, PN40, PN63, ANSI 150, ANSI 300, and ANSI 600 standards. - **Body Materials:** Choose from carbon steel or stainless steel for tailored durability. - **Valve Options:** An ISO direct mount version is available, suitable for sizes 1” to 4”. The valves can be equipped with a V ball for precise flow control, and various seat materials are offered for diverse applications. Additionally, firesafe options are available for enhanced safety. - **Actuator Options:** Select from double acting or spring return configurations (either fail close or fail open). Options for stainless steel bodies and painted finishes are also available. Invest in the Valpres Figure 72 series wafer pattern full bore ball valve for optimal performance in your applications. With its flexible design and various options, it caters to a wide range of industrial needs.

Refrigeration service valves are vital components in refrigeration systems, designed to simplify maintenance, servicing, and troubleshooting. These valves enable the isolation and control of refrigerant flow to specific areas of the system, thereby facilitating essential tasks such as charging, evacuating, and diagnosing without the need to shut down the entire system.
