Reinforced-wall PVC-U, CPVC, or PP shutoff rated for the upper end of plastic piping pressure — bubble-tight quarter-turn control on high-pressure water, chemical, and process lines.
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 High Pressure Plastic Ball Valves Manufacturers and Custom High Pressure Plastic 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.

High pressure plastic ball valves are quarter-turn shutoff valves built with thicker body walls, a reinforced stem, and a heavier union or flange connection than standard-duty PVC-U, CPVC, or PP valves, raising the working pressure rating to suit demanding process and utility lines. The floating ball and PTFE seat sealing principle is unchanged, but every load-bearing dimension is increased to keep the valve within safe stress limits at pressures that would exceed a standard-wall valve's rating.
This valve is specified wherever a line's design pressure sits near the upper range typically associated with plastic piping — high-pressure water distribution, pressurized chemical transfer, pump discharge lines, and test rigs — rather than for applications that would normally call for a metal valve on pressure grounds alone. Reinforced true union or flanged connections keep the valve serviceable in place, and the same PVC-U, CPVC, or PP material options preserve the chemical resistance and corrosion-free service life expected from plastic valves.
Lines running near the top of plastic piping's typical pressure range benefit from a valve built with additional wall thickness and a reinforced stem.
Material selection still governs chemical compatibility and temperature range, while the reinforced wall thickness delivers the elevated pressure rating across all three options.
| Material | Temperature Range | Typical Strengths | Common Use |
| PVC-U (reinforced) | 0°C to 60°C | Broad chemical resistance with added wall thickness for higher pressure | High-pressure water and cool chemical transfer |
| CPVC (reinforced) | 0°C to 90°C | Higher temperature ceiling than PVC-U with the same pressure reinforcement | High-pressure hot water and elevated-temperature chemical lines |
| PP (reinforced) | 0°C to 90°C | Good solvent resistance, lighter than reinforced PVC-U or CPVC | High-pressure dosing and general chemical processing |
| Item | Description |
| Valve Type | Two-way high-pressure plastic ball valve, reinforced body |
| Body Material | PVC-U, CPVC, or PP (reinforced wall sections) |
| Ball Material | PVC-U, CPVC, or PP (matching body material) |
| Seat Material | PTFE / reinforced PTFE |
| Seal Material | EPDM / FPM (Viton) |
| Size Range | DN15 – DN80 (1/2 inch – 3 inch) |
| End Connection | Reinforced true union (socket / threaded) or flanged |
| Working Pressure | Up to 300 psi (20 bar) at 20°C, rating decreases with temperature |
| Working Temperature | 0°C to 90°C, depending on material selected |
| Sealing Performance | Bubble-tight (zero-leakage) shutoff |
| Operation | Manual lever standard; ISO 5211 pad for actuator mounting |
| Stem Design | Reinforced stem and blow-out-proof retention for high-pressure service |
Both share the same floating ball sealing principle; the difference is how much pressure margin the body and stem are built to handle.
| Factor | High Pressure Plastic Valve | Standard-Duty Plastic Valve |
| Working Pressure | Up to 300 psi (20 bar) | Typically up to 220–235 psi (15–16 bar) |
| Wall Thickness | Increased for higher pressure margin | Standard wall thickness for the size |
| Stem Design | Reinforced, blow-out-proof retention | Standard stem retention |
| Weight | Somewhat heavier for the same nominal size | Lighter for the same nominal size |
| Cost | Higher due to added material and reinforcement | Lower for equivalent size and material |
| Best Use | Lines running near the top of plastic piping's pressure range | General-duty water and chemical service |
Thicker body walls and a reinforced stem retention system support the elevated pressure rating around the same floating-ball sealing arrangement.
High-pressure units undergo an extended pressure test sequence beyond the standard hydrostatic check to confirm the elevated rating.
The reinforced body retains a standard ISO 5211 mounting pad, so a manual lever can later be replaced with an actuator without changing the valve.
| Operation Type | Best Suited For | Key Characteristics |
| Manual Lever | Local, infrequent on/off operation on high-pressure lines | Lowest cost, no power source required |
| Pneumatic Actuator | Automated high-pressure process or dosing lines | Fast response with compressed air available |
| Electric Actuator | Remote or precise control on high-pressure headers | 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 wooden crates with reinforced padding for the heavier body.
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.
