Dereve offer a large range of pressure regulators and governors and can supply regulators with either brass, chrome plated brass or plastic bodies.

Outlet pressures available range from 200mbar-6 bar, with inlet pressures up to 35 bar.

 




"Mini" PLASTIC PRESSURE REDUCING VALVES - Model WRP2
The Dereve water pressure valve plastic WRP2 has been developed for low flow situations; capacity up to 10 lpm (2.2gpm).
The connection arrangement allows the standard body to have a variety of connections to be fitted.
1/4' & 1/2" BSP for 15mm compression fittings and plain stubs are standard.

1/2 PLASTIC PRESSURE REGULATOR - Model WRP4
The Dereve WRP4 is an all PLASTIC version of the WR4 Brass series with similar characteristics and performance at considerably less cost.
Available with 1/2" BSP female connections
Maximum Inlet Pressure = 10/35 Bar
Maximum Flow = 18LPM
Outlet Pressure Range = 0.2 - 5 Bar
Maximum Temp = 60 degrees Celsius

1/2" & 3/4" BRASS PRESSURE REGULATOR - Model WR4 & WR5
The Dereve 1/2" BSP WRA 7 3/4" BSP WR4 pressure reducing valve are designed for use on water installations to control outlet pressure down to 0.2 bar (3 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.
Max Inlet Pressure - 1/2" & 3/4" = 10.35 Bar
Outlet Pressure Range - 1/2 = 0.2 - 6.0 Bar, 3/4" = 0.2 - 5.0 bar
Maximum Flow - 1/2' = 23LPM, 3/4 = 35 LPM
Maximum Temperature - 80 degrees Celsius.

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