Plastic valves are vital components in fluid control systems, regulating the flow of liquids and gases in applications such as water treatment, chemical processing, irrigation, and HVAC. To ensure reliable operation under varying pressures, temperatures, and environmental conditions, rigorous testing is essential. Shijiazhuang Zhongshi Testing Machine Co., Ltd develops specialized testing equipment designed to evaluate the performance, durability, and safety of plastic valves, aligning with international standards to support manufacturers in delivering compliant and dependable products.
Plastic valves must maintain precise control, resist wear, and prevent leaks throughout their service life. Failures can lead to system inefficiencies, contamination, or safety risks. Testing validates critical parameters such as pressure tolerance, cycle durability, seal integrity, and resistance to chemical or thermal degradation. Compliance with standards like ISO 9393, ASTM F1986, and GB/T 27726 ensures valves meet performance requirements for industries ranging from municipal water systems to industrial processing.
Shijiazhuang Zhongshi offers a comprehensive suite of testing systems tailored to assess plastic valve performance:
Hydrostatic Pressure Testers
These systems subject valves to sustained internal pressure, simulating operational conditions in water or gas systems. Tests measure leakage rates, deformation, and long-term pressure resistance.
Cycle Life Testers
By automating repeated opening and closing cycles, these machines evaluate a valve’s mechanical durability and wear resistance over extended use.
Burst Pressure Testers
Designed to determine the maximum pressure a valve can withstand before failure, these testers provide critical safety data for high-pressure applications.
Seal Integrity Testers
Using air or liquid under pressure, these systems detect micro-leaks in valve seals, ensuring airtight and watertight performance.
Environmental Stress Chambers
Chambers simulate extreme temperatures, UV exposure, or chemical exposure to assess a valve’s resistance to aging and environmental stressors.
Torque and Actuation Testers
These measure the force required to operate manual or automated valves, ensuring smooth actuation and compliance with ergonomic standards.
Flow Rate Testers
By quantifying a valve’s flow capacity under specific pressures, these systems validate its efficiency in regulating fluid dynamics.
Shijiazhuang Zhongshi’s equipment integrates advanced technologies to deliver precise and repeatable results:
Automated Control Systems: Programmable logic controllers (PLCs) enable precise regulation of pressure, temperature, cycle counts, and test durations.
Real-Time Data Acquisition: Software records test parameters, generates pressure-time curves, and produces compliance-ready reports.
Adaptable Fixtures: Modular clamps and connectors accommodate various valve types (e.g., ball, butterfly, diaphragm) and sizes.
Safety Mechanisms: Emergency pressure release valves, protective enclosures, and overload sensors ensure operator safety during high-risk tests.
Modular Design: Systems can be upgraded with additional sensors, software modules, or environmental simulation capabilities.
Plastic valve testing equipment serves sectors where precision and reliability are non-negotiable:
Water and Wastewater: Ensuring valves in treatment plants and distribution networks resist corrosion and maintain leak-proof operation.
Chemical Processing: Validating valves for compatibility with aggressive fluids and high-pressure conditions.
Agriculture: Testing irrigation valves for UV resistance and durability under cyclic pressure.
HVAC: Certifying valves for thermal stability and efficient refrigerant control.
Industrial Manufacturing: Assessing valves used in process control systems for abrasive or high-temperature media.
Shijiazhuang Zhongshi provides flexible testing configurations to address specific challenges:
Multi-Standard Compliance: Equipment aligns with ISO, ASTM, GB, and regional standards to meet global certification requirements.
Tailored Testing Protocols: Customizable setups for specialized evaluations, such as accelerated aging tests or chemical resistance studies.
Scalable Systems: Modular components allow future expansions, such as integrating higher-pressure pumps or advanced data analytics tools.
Each testing system undergoes rigorous calibration and validation processes. Components are sourced from certified suppliers, and final equipment is tested against industry benchmarks to ensure accuracy. This commitment enables clients to achieve certifications required in regulated markets, including CE, ISO, and ASME compliance.
Shijiazhuang Zhongshi prioritizes long-term partnerships through comprehensive support:
Technical Training: On-site or virtual sessions to optimize equipment operation, maintenance, and safety practices.
After-Sales Assistance: Timely access to spare parts, software updates, and troubleshooting to minimize downtime.
Custom Engineering: Collaborative development of testing solutions for innovative valve designs or novel materials.
