Gresswell have designed the FIG 550 as a straight through type valve that is held closed by the action of a built-in spring and soft seat.

Fluid is allowed to flow through the valve, as the valve is opened by hand or foot pressure on the level. The release of the pedal reverts the valve back to a closed position.

The Gresswell FIG550 is found most commonly in laundries and showers, but can also be used on various oils and fluids coupled with a suitable resilient seat.
