Characteristic Description
Material Composition
The seat seal adopts TPE (Thermoplastic Elastomer) for excellent flexibility and tight sealing, while the ball is made of PP (Polypropylene) to guarantee smooth fluid flow and wear resistance. The handle is constructed from ABS plastic, offering a sturdy grip and impact resistance, and the O-ring seal is made of NBR (Nitrile Butadiene Rubber) to enhance leak-proof performance under varying pressures.
Structural Design
This ball valve features two distinct shape options: octagonal and compact, catering to different installation spaces and aesthetic preferences. It also provides two connection methods—threaded and socket—to accommodate diverse piping systems. A key structural innovation is the built-in O-ring seal within the valve body (instead of the handle), which integrates all sealing components through precision molding, significantly reducing leakage risks compared to traditional designs.
Market Research
The global PVC ball valve market is witnessing steady growth, driven by the rising demand for durable, cost-effective fluid control solutions in industries such as water treatment, chemical processing, and construction. Industrial sectors, in particular, prioritize valves with high-pressure resistance and reliable sealing—two core strengths of the HJ UPVC ball valve. North American and European markets, in line with ASTM and DIN standards, have strict requirements for product quality and safety, while Asian markets value versatility and easy maintenance. This product’s compliance with multiple international standards and user-friendly design positions it to capture opportunities across these regions.
Key Features
Superior Sealing Reliability: The integrated mold-assembled sealing structure (O-ring inside the body) eliminates loose components, ensuring leak-proof operation even under 16pn water pressure equivalent.
Effortless Maintenance: The detachable handle allows for quick replacement or addition of an extra O-ring seal, minimizing downtime and repair costs.
Smooth Bi-Directional Operation: For sizes 2.5" and above, the optimized mold design enables bidirectional opening, with lighter torque and smoother handle rotation compared to conventional valves.
Comprehensive Quality Testing: Each unit undergoes rigorous high-pressure air testing—held for 24 hours—to verify pressure resistance and leakage, ensuring zero defective products reach customers.
Performance Meets
This HJ PVC ball valve fully complies with international standards including ASTM, DIN, JIS, and BS, meeting the technical requirements of global markets. It performs exceptionally in pressure resistance (equivalent to 16pn water pressure), temperature stability, and corrosion resistance, adapting to fluids such as water, chemicals, and neutral liquids. The torque optimization for large sizes ensures easy operation without compromising structural integrity, making it suitable for both manual and semi-automatic control systems.
Customized Service
HJ offers flexible customization to meet specific customer needs:
Size customization: Adjustments within the 1/2" - 8" range to fit unique piping specifications.
Connection type customization: Tailored threaded or socket connections based on installation requirements.
Shape customization: Choice between octagonal and compact designs, or modified dimensions for limited installation spaces.
Branding customization: Laser engraving of customer logos or part numbers for brand recognition.
FAQ
Q1: What is the maximum pressure this valve can withstand?
A1: The valve is tested to withstand pressure equivalent to 16pn water pressure, making it suitable for most industrial and commercial low-to-medium pressure applications.
Q2: Can it be used with chemical fluids?
A2: Yes. The UPVC body, PP ball, and NBR O-ring are corrosion-resistant to most neutral and mild chemical fluids. For strong acids or alkalis, contact our team for material modifications.
Q3: How often should the O-ring be replaced?
A3: Under normal use, the NBR O-ring has a service life of 3-5 years. Regular inspection (every 6-12 months) is recommended; replace if signs of wear or leakage appear.
