Universal Valve Test Bench DN15-DN250 300 Bar Water Pressure 6.9 Bar Air Pressure 60T Clamping Force Valve Testing Equipment

Universal Valve Test Bench DN15-DN250 300 Bar Water Pressure 6.9 Bar Air Pressure 60T Clamping Force Valve Testing Equipment

Product Introduction

The universal valve test equipment is a specialized testing solution composed of three core components: a control console, a clamping table, and a protective cover. It is specifically designed to conduct rigorous performance evaluations on high-pressure and medium-pressure valves, including gate valves, ball valves, globe valves, and other straight-through flange or welded structure valves. The equipment adheres to international testing standards and ergonomic design principles, ensuring not only the accuracy and reliability of test results but also the safety and comfort of operators during long-term use. With its efficient energy-saving system, it delivers stable performance while enabling enterprises to achieve rapid return on investment and sustainable operational benefits. It is widely applicable in industries such as petroleum, chemical, water conservancy, power, and machinery manufacturing, providing critical quality assurance for valve production, maintenance, and certification.

Product Features

• Ergonomic & Safe Operation: Complies with human engineering design standards to reduce operator fatigue during prolonged use; integrated with multiple safety protection mechanisms, including clamping self-locking function, full-enclosed safety protective cover, and overpressure automatic shutdown device, effectively eliminating potential operational hazards.
• Efficient & Energy-Saving Performance: Optimized hydraulic and pneumatic system design minimizes energy consumption without compromising testing efficiency, realizing cost reduction for long-term operation and quick investment return.

Technical Parameters

Test Objects & Detection Items

Test Objects

• Flange-type valves: Gate valves, ball valves, globe valves, check valves, butterfly valves, etc.
• Threaded-type valves: Small-diameter gate valves, ball valves, globe valves, etc.
• Welded-type valves: High-pressure gate valves, ball valves, globe valves for industrial pipelines, etc.
• Application-specific valves: Valves for petroleum, chemical, water conservancy, power, and construction industries.

Detection Items

1. Seat Tightness Test: Verify the leakage of the valve seat under specified test pressure, ensuring no excessive leakage when the valve is fully closed.
2. Shell Strength Test: Detect the pressure-bearing capacity of the valve shell, preventing deformation or rupture under rated working pressure.
3. Valve Stem Sealing Test: Check the sealing performance of the valve stem packing or seal ring to avoid medium leakage through the valve stem.
4. Opening/Closing Performance Test: Evaluate the flexibility and smoothness of the valve's opening and closing actions under test pressure.
5. Pressure Retention Test: Maintain the test pressure for a specified time to verify the long-term pressure-bearing stability of the valve.
