Plastic Valve Testing Equipments: Ensuring Functional Integrity Under Pressure and Flow Conditions

Plastic valves are key control elements in fluid transport systems, including water supply, wastewater treatment, chemical processing, and agricultural irrigation. As these valves are responsible for regulating flow, their performance directly impacts the reliability and safety of the entire system. Shijiazhuang Zhongshi Testing Machine Co., Ltd. develops and manufactures plastic valve testing equipments that help validate valve durability, sealing capacity, and operational consistency.

Testing Functions

• Seal Tightness Testing: Evaluates whether valves fully prevent flow under closed conditions using water or air pressure.

• Opening and Closing Torque Testing: Measures the required force to operate the valve, useful for verifying ease of operation under pressure.

• Pressure Resistance Testing: Applies increasing internal pressure to determine the valve’s tolerance limits.

• Cycle Life Testing: Simulates thousands of open-close cycles to assess the valve’s long-term mechanical reliability.

• Flow Rate Analysis: Tests the flow characteristics and pressure drop across the valve in both open and throttled conditions.
