1) Safety valves are overpressure protection devices for protecting personnel and equipment, and usually installed in HP operation line for cementing/fracturing pumps, pressure vessels and other equipment under HP and high displacement.
2) The preset pressure value ranging 5000psi to 15000psi(35MPa to 105MPa) is adjusted through the top nut. When pumping pressure or operating pressure exceed the preset value, the safety valves will automatically open for pressure release. While the pressure is less than the preset value, they will be automatically closed.
3) The model of safety valve available: AQF02-105, AQF02-42,rated: 6000psi(42MPa)-15000psi(105MPa).
Construction, connecting mode and size are same as SPM equivalent products;
The butterfly spring inside can realize opening/closing of valves, therefore safety valves can protect people and equipment without shutting down relevant equipment. They are more reliable than shear type safety valves.

Our pressure relief safety valve is designed as a pop up type valve. On exceeding set pressure the valve opens to discharge the excess built up pressure.
After relieving excess pressure, the valve automatically returns to the original position. The bronze internals (Seat & Plug) ensure that there is no leakage while in operation.
By replacing only the spring it is possible to change set pressure range.

Three way valve which design for diverting or mixing service applications. A diverting service valve takes common stream and splits it into two outlet force, this configuration is used for applications such as level control and pump bypass control valve.
Mixing service valve combines two fluid streams and discharges the mixed fluid to a common outlet ports this configuration is used for applications where two fluids need to be mixed the end result can range from temperature control to producing a new fluid.
Three way valve actually performs of two opposite acting standard two way valves. So that use of one valve instead of two is very economical.
Valves are available with hand wheel if required.

PRDS Valves ( Combined Pressure Reducing Cum Desuperheating Valves )
Features :
Our combine PRDS valve is a single seated globe type valve that combines pressure & temperature reduction in one compact solution. The high pressure, high temperature steam which enters the main branch, is reduced in pressure and then spray water is injected immediately after pressure reduction.
The high velocity and turbulent flow conditions data present immediately following the pressure reduction allow for rapid atomization and absorption of the spray water thus effectively desuperheating the steam.
Reduction of noise level due to mist formation by water is an added advantage.
