Reliance RWC 100 Series Pressure Relief Valve 3/4" x 1" F x F 3 Bar - PREL100014

Features & Benefits

• Single unit Y-Pattern globe valves with an integrated orifice plate, designed to create a fixed orifice flow measurement unit, providing both regulation and isolation capabilities. • The Double Regulating feature enables the valve to be used for isolation and allows it to return to its pre-set position, ensuring the desired flow rate is maintained. • Flow measurement accuracy of ±5% is guaranteed at all open positions of the valve in line with BS 7350: 1990 standards. • Ideal for injection or other circuits that require a double regulating valve for effective system balancing. • Finished with an external spray epoxy coating for enhanced durability.

Specification

• Y-Pattern globe valves designed for flow regulation and isolation, equipped with Figure 631 test points for effective flow measurement. • These valves meet the specifications of BS 7350, with flanged ends conforming to BS EN 1092-2 (formerly BS 4504).

Pressure/Temperature Rating

• PN16 / -10 to 120°C • Ratings comply with BS EN 1092-2 PN16 (previously BS 4504).

The Reliance Valves Aquasystem Stainless Steel Expansion Vessel is specifically designed for heating applications. Available in capacities ranging from 2 litres to 5000 litres and with maximum pressure ratings between 8.0 and 10.0 bar, these vessels feature replaceable membranes. The Aquasystem range allows for servicing on-site, ensuring that water does not come into contact with the steel expansion vessel shell, which helps to prevent internal corrosion and extend the vessel's lifespan.

Features and Benefits:

• Durable stainless steel bolted flange that prevents corrosion.
• Extra-wide membrane opening to minimise noise caused by restricted flow.
• Internal membrane design eliminates water contact with the steel shell, thus preventing internal corrosion.
• A comprehensive range from 2 to 5000 litres suitable for various applications.
• All models come with replaceable membranes for convenient servicing without removal.
• Pre-charge valve included for easy topping up of air pressure.
• Designed exclusively for heating applications.
