DescriptionGOK ANTI-SIPHON VALVEThis GOK anti-siphon valve is designed for use on oil tanks for domestic oil-fired central heating systems, this valve will prevent the flow of fuel when there is no positive vacuum applied to the downstream side. This prevents theft of fuel by cutting the pipe and also prevents pollution if the pipe downstream of the valve rupturesAdjustable between 0 and 4 meters negative head, this equates to 0 to – 400MBBrass Body, with Nitrile DiaphragmOnly available in 3/8″ BSPMax Flow – TBCTip: Consider the option of using the ‘Tank Top‘ (see separate option), which is an all-in-one device incorporating an anti-siphon valve, filter, etc all in one complete unit (eliminating the risks of air leaks that can be introduced when connecting all of the individual components). The Tank Top also comes complete with a floating suction line to ensure the oil is sucked up from the top of the fluid in the tank minimising the risk of pulling through debris/particulate/water that may be collected in the bottom of the tank. The Tank Top gives superior protection against the introduction of air leaks and at the same time significantly reduces the complexity and time take for installation.
