Reliance RWC 103 Series Pressure Relief Valve With Gauge Port 15mm x 15mm 3 Bar - PREL103005
The PREL103005 Sealed Pressure Relief Valve (PRV) with a 1/4" Gauge Port (valve supplied without gauge) effectively discharges water from the system at a predetermined pressure, in the event of over-pressurisation within your heating system. The Reliance Valves 103 Series Sealed Heating System Pressure Relief Valve is primarily designed as a critical safety component within sealed heating systems. Upon installation, the pressure relief valve is calibrated to an appropriate pressure. If the system pressure exceeds this set point, the valve activates and releases excess pressure into the atmosphere, thereby preventing the pressure from escalating to potentially hazardous levels that could not only damage the heating system but also pose risks to individuals nearby.
**Features and Benefits:**
- Diaphragm design enhances resistance to scaling, prolonging the valve's lifespan
- Easy removal of the single-piece cartridge allows for straightforward cleaning or cartridge replacement
- Set relief pressure range of 3.0 bar
- Available with 15mm connections for installation versatility
- Designed exclusively for heating applications
**Specification:**
- Size: 15mm x 15mm
- Connections: Compression Inlet x Compression Outlet
- Materials: Hot pressed DZR Brass
- Medium: Water
- Set Pressure: 3 Barg
- Temperature: +140°C
- Product Code: PREL103005
- Notes: WRAS approved, includes a 1/4" Gauge port (valve supplied without gauge)
Investing in the PREL103005 sealed PRV ensures the safety and integrity of your heating system, providing peace of mind and reliable operation.

FSGGRG - Graphite Rupture Discs
The FSGGRG Graphite Rupture Discs are replaceable and designed for mounting on either graphite holders (rated for pressures up to 10 bar g) or metal holders (up to 15 bar g). These highly versatile discs cater to a wide range of applications and are particularly efficient in handling aggressive fluids while exhibiting low sensitivity to temperature variations at bursting pressures. Constructed from ultra-pure graphite, the discs are impregnated with phenolic resins, which enhance their impermeability. When ruptured, they provide a complete opening while fragmenting into manageable pieces. For rupture pressures below 1.7 barg, vacuum support is necessary; however, these discs are self-supporting at higher pressure calibrations.
