PRESSURE CONTROL VALVES
SLOFLO CONTROL VALVE

"Sloflo" CONTROL VALVE

The "Sloflo" Control Valve is designed for use on Automatic Flushing Cisterns. Eliminates the waste of water by fitting this control to automatic flushing toilets. This control only allows water to be used for cleansing when the other toilet facilities are in use. Night times, weekends, holidays etc., the control only allows a flush of water at pre-set intervals for keeping the men's toilets fresh and clean. This product is marketed in the U.K. by Waterfuse Ltd.

BRASS WATER GOVERNOR

1/2" BRASS WATER GOVERNOR - MODEL WG4

The Dereve "WG4" range of pressure control valves (or "water governors")of the diaphragm type, with outlet pressure/flow adjustment screw (with locknut), having chromium plated DZR bodies. Maximum inlet pressure 10 bar and maximum flow 23 LPM. The valve is not suitable for pressure control in a no-flow situation. Size 1/2" BSP female connections.

1/2" & 3/4" BRASS PRESSURE REDUCING VALVES

The Dereve type WR4/5 pressure reducing valves are designed for use on water installations to control outlet pressures down to 0.2 bar (2 psi). When the outlet flow is reduced to zero the valve "locks up", i.e. does not allow the outlet pressure to rise appreciably above the set outlet pressure. The body material is DZR Brass, together with other exposed brass components is chrome plated to increase corrosion resistance.
