This HYTEK Engineered anti-syphon (pressure regulating) valve is a must to prevent above ground diesel and HVO bulk fuel storage tanks from emptying if the dispensing pump or pipework is damaged. An environment must, helps to prevent the accidental emptying of the bulk fuel storage tank. 

It is fully adjustable depending on the height of the tank/head pressure of fuel to ensure the dispensing pumps are not being overworked and to prevent fuel from coming out of the pump unit air separator outlet valve. It helps to prevent fuel loss and fuel contamination. 

Easy to install as it comes with 1½" female BSPT flanged inlet and outlet ports. Supplied with an inlet strainer to prevent contamination inside the valve to prolong the internal diaphragm life.

It must be mounted horizontally or vertically near the fuel dispenser (see instructions).

UK made casting is assembled and tested in the HYTEK factory, just a 10-minute drive from London Stansted Airport.
