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.

Range of application: applicable for the set-pressure, setback pressure and sealing tests of direst loaded and pilot-operated safety valves.
Technical Parameters:
Maximum drift diameter: DN400mm
Maximum test pressure: 60Mpa
Pressure test precision: pressure gauge of 0.4 grades (Users can choose a more precise one.)
Test medium: nitrogen, compressed air or clean water (Gas liquid dual-capable one can be designed.)
Functions and Characteristics:
The equipment has advanced design principle. It uses pneumo-hydraulic booster pump as its clamping pressure source and air driven gas booster pump as its test pressure source. A gas cylinder is equipped, which enables the test to be conducted continuously.
â?¢The test pressure is adjustable and the process of pressurization is stable.
â?¢Clamping pressure source and test pressure source can use imported booster pumps from America or Germany, which have a wide range of output pressure.
â?¢All the manual high pressure valves, pipe fittings and connectors are imported ones, which guarantee their pressure levels, safety and reliability. Most gas and liquid media are available.
MAQ-400 /48BA Functions and Characteristics:
Maximum drift diameter: DN400mm
Maximum test pressure: 48Mpa
Pneumatic control hydraulic clamping device is adopted. Clamping force is adjustable. The equipped pressure gauge displays the corresponding clamping force and provides a comparison table between the pressure and the clamping force, which facilitates operators to choose appropriate lamping force according to the safety valve calibration pressure and the drift diameter.
All the valves, pipe fittings and connectors are made of stainless steel.
The test is operated manually and operators record the data.
The system includes two test and calibration tables. One is equipped with two clamping devices. There are totally three clamping devices: one is for safety valves of DN15-DN100; one is for safety valves of DN100-DN200; one is for safety valves of DN200-DN400.
â?¢Various test tools are equipped to meet the needs of customers on different kinds of safety valves.
A safety valve is becoming increasingly popular among different industrial communities. The reason for such increased demand due to its ability to control and check the pressure of fluids along with diverting the routes for transporting them in designated outlets. These valves are made of various durable metals and can withstand high temperature till a specific limit. Safety relief valve helps in regulating fluid movements. For checking pressure, there is no better alternative than pressure relief valve. When it comes to checking boiler temperature then thermal relief valve is the best.
