Pressure Valves

The Ridart anti-syphon (pressure regulating) valves cope with higher fuel dispensing pump flow rates of up to 200 litres per minute. Fully adjustable depending on the height of the tank/head pressure of fuel, this anti-syphon (pressure regulating) valve ensures the dispensing pumps are not being overworked and prevents fuel from coming out of the pump unit air separator outlet valve. It helps to prevent fuel loss and fuel contamination. This anti-syphon (pressure regulating) valve is easy to install as it comes with 1½" female BSPT flanged inlet and outlet ports.

The Pressure Relief Angle Check Valve is a brass non return valve for keeping a pump’s suction line primed. It ensures the pressure from the fuel head is held back from the pump. This angle check valve can be used in conjunction with a hose reel thanks to the integrated pressure relief valve.

The Adjustable Pressure Relief Valve is to be installed to complement pumps that have no internal bypass valve. The adjustable valve is designed to relieve excess liquid pressure back to the tank for applications requiring a nozzle to be used. Pressure gauges should be installed on the inlet to set the opening pressure for the pumping system.

Not to be used as a bypass recirculation system under constant pressure.

The Plastic PRV Tank Vent Valve is a poppet type valve designed to stop fuel vapours from escaping under usual operating conditions. This plastic constructed pressure vacuum vent valve is used on static and mobile fuel storage tanks, and comes with a sealing ‘o’ring and metal stem.

The Metal PRV Tank Vent Valve has an integrated poppet type valve designed to prevent fuel vapours from escaping under normal operating conditions. This Teflon coated aluminium pressure vacuum vent valve is fitted on top of risers on stage 1B vapour recovery systems and static tanks.

The Pressure Regulating Anti-Syphon Valve from Lafon ensures the smooth running of a pumping system connected to an above ground storage tank. This pressure regulating valve is designed to avoid accidently emptying the tank by overloading the pump and delivery system, thereby limiting product loss and site pollution.

Constructed from aluminium and copper-aluminium alloy with special hydrocarbon seals, the pressure regulating valve prevents head loss and regulates and stabilises the flow with no hammering effect. Thanks to their tri-flange connection, these pressure regulating valves can be removed and serviced without disturbing the installation’s pipe work.

The GOK Pressure Regulating Valve is designed for use on single appliance gravity feed systems, primarily oil heating, with a liquid head range between 2metres and 30metres. These pressure regulating valves have a fixed outlet pressure of 100 mbar for flow rates up to 20litres per hour.
