Quarter-turn CPVC shutoff rated for hot water and elevated-temperature chemical lines — broad chemical resistance with a temperature ceiling well above standard PVC-U.
Ningbo Baodi Plastic Valve Co., Ltd. traces its origins back to 1979, with its predecessors being Zhenhai Chemical Valve Factory and Beilun Plastic Valve Factory. The company is one of the earliest Industrial CPVC Ball Valves Manufacturers and Custom Industrial CPVC Ball Valves Factory in China to design and produce industrial plastic valves and receive acceptance from the Ministry of Chemical Industry. In 1979, the company manufactured its first plastic diaphragm valve, which passed the technical appraisal of the Ministry of Chemical Industry in 1983. In 1992, the company invented the one-piece flange ball valve, a structural design that has since become the most widely used plastic valve product in chemical-related industries. The development history of the company and its predecessors also represents an important chapter in the application of plastic valves in China's industrial production.
In 2006, the company expanded its product line to cover industrial plastic pipes and fittings, becoming one of the first domestic enterprises to apply CPVC material in the production of industrial-grade piping valves. Over more than 40 years since its establishment, the company has designed and manufactured various plastic valves for the most demanding industries. It has served tens of thousands of enterprises both domestically and internationally, exporting to more than 60 countries, and has consistently remained a leading manufacturer of industrial thermoplastic valves and piping systems. Our professional service and stable quality have always been well received and recognized by customers.
Baodi ranks among the global leaders in the number of product categories, capable of fully covering industrial plastic pipe and valve requirements. The company has obtained ISO 9001, ISO 14001, and ISO 45001 system certifications, as well as the national special equipment pressure piping component manufacturing license. It is recognized as a National High-Tech Enterprise and a Ningbo City Specialized and Sophisticated Enterprise. Baodi is a principal drafter of the national standard for plastic diaphragm valves and the chemical industry standards for plastic diaphragm valves, plastic ball valves, and plastic check valves.

Industrial CPVC ball valves are quarter-turn shutoff valves molded from chlorinated polyvinyl chloride, a material that keeps most of PVC-U's broad chemical resistance while raising the usable temperature ceiling to around 95°C. That difference makes CPVC the material of choice wherever a plastic valve has to hold up to hot process water, elevated-temperature acids and alkalis, or hot water distribution — duty that would soften or distort a standard PVC-U body over time.
Most industrial CPVC ball valves use a true union body, so the center section with the ball and seats can be lifted out of the line for cleaning or seat replacement without cutting the surrounding CPVC pipework. A floating ball paired with PTFE or reinforced PTFE seats delivers bubble-tight shutoff, while socket or threaded end connections keep the valve compatible with standard CPVC pipe and fittings used across process and hot-water piping systems.
CPVC is chosen wherever the fluid temperature would push a PVC-U valve beyond its safe operating range.
Choosing CPVC over PVC-U, PP, or PVDF comes down to the temperature and chemical profile of the line it protects.
| Material | Temperature Range | Typical Strengths | Common Use |
| CPVC (this valve) | 0°C to 95°C | High-temperature version of PVC chemistry, strong acid/alkali resistance | Hot water, elevated-temperature chemical lines |
| PVC-U | 0°C to 60°C | Similar chemical resistance, lower cost | Cool-service water and chemical transfer |
| PP | 0°C to 90°C | Good solvent resistance, lighter weight | Dosing and general chemical processing |
| PVDF | -20°C to 99°C | Superior resistance to strong oxidizers and halogens | High-purity and aggressive chemical duty |
| Item | Description |
| Valve Type | Two-way true union CPVC ball valve |
| Body Material | CPVC |
| Ball Material | CPVC |
| Seat Material | PTFE / reinforced PTFE |
| Seal Material | EPDM / FPM (Viton) |
| Size Range | DN15 – DN100 (1/2 inch – 4 inch) |
| End Connection | Socket (solvent weld) or threaded (BSP / NPT) |
| Working Pressure | Up to 230 psi (16 bar) at 20°C, rating decreases with temperature |
| Working Temperature | 0°C to 95°C |
| Sealing Performance | Bubble-tight (zero-leakage) shutoff |
| Operation | Manual lever standard; ISO 5211 pad for actuator mounting |
| Union Design | True union body for tool-free removal from the line |
The two materials look and install the same way, but their working temperature ranges set them apart.
| Factor | CPVC Ball Valve | PVC-U Ball Valve |
| Maximum Temperature | About 95°C | About 60°C |
| Chemical Resistance | Comparable broad resistance to acids and alkalis | Comparable broad resistance to acids and alkalis |
| Hot Water Suitability | Suitable for domestic and process hot water | Not recommended above roughly 60°C |
| Cost | Somewhat higher than PVC-U | Lower cost for cool-service lines |
| Pipe Compatibility | Solvent-welds or threads to CPVC pipe and fittings | Solvent-welds or threads to PVC-U pipe and fittings |
| Mechanical Strength | Slightly higher strength retention at elevated temperature | Strength drops off faster as temperature rises |
The true union CPVC body houses the ball, seats, and stem assembly, with union nuts allowing removal for service.
Inspections confirm both sealing performance and dimensional accuracy, with attention to CPVC's higher-temperature service.
A standard ISO 5211 mounting pad allows manual operation to be upgraded to pneumatic or electric actuation later.
| Operation Type | Best Suited For | Key Characteristics |
| Manual Lever | Local hot-water or process shutoff | Lowest cost, no power source required |
| Pneumatic Actuator | Automated hot-process lines with compressed air available | Fast cycling for sequencing or batch control |
| Electric Actuator | Remote-controlled or monitored hot water and chemical lines | Integrates with control systems and remote monitoring |
Payment: T/T (bank transfer), L/C, and PayPal are accepted, with flexible terms for repeat orders. A deposit is typically required to confirm production.
Shipping: Sea freight (FCL/LCL) for large-volume orders, air freight for time-sensitive shipments, and express courier for samples. Valves are packed in cartons or wooden crates with anti-collision padding.
Delivery: Shipment from the nearest available port or airport, with door-to-door, FOB, CIF, or EXW terms on request.
Each valve is covered under a standard warranty against manufacturing defects in material and workmanship, generally valid for 12 months from the shipment date.
