Plastic Valve Testing Equipments

Valves regulate flow, pressure, and direction within piping networks. Plastic valves—made from PVC, CPVC, PP, and PVDF—are prized for chemical resistance and corrosion protection. Rigorous testing ensures valves operate reliably under mechanical stress, temperature variation, and fluid dynamics. Shijiazhuang Zhongshi Testing Machine Co., Ltd. offers specialized plastic valve testing equipments engineered for comprehensive performance evaluation.

Primary Test Capabilities

• Leakage and Seat Tightness: Low‑ and high‑pressure leak tests evaluate seat and stem seals. Bubble detection or mass flow meters quantify leakage rates to as low as 0.001 mL/min.

• Shell and Seat Strength: Burst and proof pressure tests validate valve body and internal components. Automated sequences ramp pressure to proof level, hold, and then ramp to burst, per ISO 9393 and API 598.

• Cycle Testing: Automated actuators open and close valves through thousands of cycles, tracking torque, opening/closing time, and leak rates after each cycle to simulate service life.

• Temperature and Pressure Shock: Rapid temperature change chambers paired with pressure pulses assess valve integrity under thermal shock conditions.

Key Specifications

• Test Pressure: 0.01 MPa to 25 MPa, adjustable ramp rates

• Leakage Detection: Sensitivity down to 0.001 mL/min

• Actuation Speed: 0.1 s to 10 s per cycle, programmable dwell times

• Temperature Range: –20 °C to 120 °C for shock tests

Industry Applications

• Water Treatment: Ensuring control valves in filtration and distribution systems maintain sealing under back‑pressure

• Chemical Processing: Testing valves that handle aggressive acids, bases, and solvents under fluctuating temperatures

• Agricultural Irrigation: Validating solenoid and manual valves for drip and sprinkler systems under high cycle counts

• Pharmaceutical Manufacturing: Certifying sanitary valves for sterile fluid handling with minimal particulate generation
