Pneumatic Liquid Control Pressure Relief Valve Test Bench with Round Chart Recorder

The structural design of the fluid pressurized control cabinet is compact. Depending on specific requirements, air-driven fluid booster pumps, valves, control switches, and precision accessories are assembled in a rugged frame or closed cabinet.

This test machine is equipped with a pressure recorder capable of logging all testing pressure data, which is essential for detailed analysis and record-keeping. The pump automatically stops when output pressure reaches the preset value and restarts if pressure drops or drive air increases.

Booster pumps feature various pressure ratios, reaching a maximum operating pressure of up to 640 Mpa, making them ideal for high-pressure hydraulic operations, research, and industrial testing.

• All pipes and fittings are made of high-grade stainless steel for longevity.
• Automatic pressure maintenance without energy expenditure once preset value is reached.
• No dissipated heat during the pressure holding phase.
• Explosion-proof design, suitable for oil and gas field environments.
• Adjustable working pressure via air-driven regulation.
• Easy installation, operation, and maintenance.

This equipment is widely used for:

• Hydrostatic testing for valves, tanks, and pressure vessels.
• Gas transfer and filling (Argon, Helium, Hydrogen, Nitrogen, etc.).
• Charging of gas cylinders and accumulators.
• High-pressure gas injection systems across various industries.
• Leak testing and pressure testing for hoses, pipes, and tubing.

We provide professional advice regarding machinery, materials, and packing. Customization is available based on customer requests. All equipment comes with a two-year warranty and operation manuals.
