Hattersley 970WG PN16 Butterfly Valve - Gearbox Operated

The Resideo F78TS flanged reverse rinsing filters are designed for installations that require a high demand for water. These filters are ideal for large residential buildings, central water supply systems, and various commercial or industrial applications. The F78TS models feature the same advanced reverse rinsing filtration system found in our range of household fine filters. Additionally, they can be retrofitted with the Z11AS fully automatic reverse rinsing actuator and the DDS76 differential pressure switch. This fine filter effectively prevents the ingress of foreign materials, such as rust particles, strands of hemp, and grains of sand, thereby minimising the risk of corrosion.

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
