Safety Relief Valves
‘WB’ SERIES SPRING LOADED
SAFETY RELIEF VALVES
The WB is designed to safely relieve excess pressure in
pumps, pipework, tanks, calorifiers, gas and oil
separators and other process vessels. It is suitable for
gas, steam, vapour and liquid applications. The WB
conforms to API 526 pressure/temperature ranges,
orifice areas and dimensions.
‘SAFEFLO’ SAFETY AND
THERMAL RELIEF VALVES
Safeflo valves are designed for similar duties to the WB
but for small capacity applications.They safely relieve
thermal expansion of process fluids in vessels and long
lengths of pipework, and are suitable for gas and liquid
applications.
‘SAFESET’ PILOT OPERATED
SAFETY RELIEF VALVES
Safeset valves are self contained pilot operated safety
relief valves which use the system pressure to control
the valve opening and closing. No other source of
energy is required.
A choice of different types of Safeset pilot valves are
available, including pop and modulating action to suit a
variety of applications.

Safeset valves conform to API 526 pilot operated
pressure/temperature ranges and dimensions, with
multiple orifice areas contained within each valve
body size.
