A shortened face-to-face plastic ball valve body for dense manifolds, OEM skids, and instrument panels — full bubble-tight shutoff in a reduced footprint.
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 Compact Industrial Ball Valves Manufacturers and Custom Compact Industrial 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.

Compact industrial ball valves are quarter-turn shutoff valves engineered with a shortened face-to-face length and reduced overall envelope compared with standard true union valves, while keeping the same floating ball and PTFE seat arrangement for bubble-tight shutoff. Molded from PVC-U, CPVC, or PP, the smaller body and lighter weight make it easier to fit valves into densely packed manifolds, instrument panels, and skid-mounted equipment where standard-length valves would not fit.
Because floor space, panel depth, or manifold spacing is often the limiting factor on packaged equipment, a compact body lets designers place more valves in the same footprint or route pipework tighter without sacrificing flow area or sealing reliability. The valve still accepts standard socket or threaded end connections and can be specified with a true union or single-body design depending on whether in-line serviceability or maximum space savings is the priority.
Packaged and skid-mounted equipment is often designed around tight space budgets, where every millimeter of valve length counts.
The compact body is offered in the same core materials as standard valves, so chemical compatibility does not have to be traded off for size.
| Material | Temperature Range | Typical Strengths | Common Use |
| PVC-U | 0°C to 60°C | Broad acid and alkali resistance, economical, lightweight | General water and chemical service on compact skids |
| CPVC | 0°C to 90°C | Higher temperature tolerance than PVC-U with similar chemical resistance | Hot water or elevated-temperature compact installations |
| PP | 0°C to 90°C | Good solvent resistance, among the lightest options | Weight-sensitive mobile or panel-mounted equipment |
| Item | Description |
| Valve Type | Two-way compact-body plastic ball valve |
| Body Material | PVC-U, CPVC, or PP |
| Ball Material | PVC-U, CPVC, or PP (matching body material) |
| Seat Material | PTFE / reinforced PTFE |
| Seal Material | EPDM / FPM (Viton) |
| Size Range | DN15 – DN65 (1/2 inch – 2-1/2 inch) |
| End Connection | Socket (solvent weld) or threaded (BSP / NPT) |
| Working Pressure | Up to 220 psi (15 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 |
| Body Style | Compact single-body or compact true union |
| Face-to-Face Length | Reduced versus standard-length equivalent valve |
Both use the same sealing principle; the compact version trades some in-line serviceability space for a smaller footprint.
| Factor | Compact Ball Valve | Standard-Length Ball Valve |
| Face-to-Face Length | Shortened for dense layouts | Standard industry dimension |
| Weight | Lighter, easing panel and skid mounting | Heavier for the same size |
| Manifold Density | More valves fit in a given header length | Fewer valves fit in the same space |
| Union Option | Available as compact true union or single-body | Typically full-length true union |
| Best Use | Space-constrained skids, panels, manifolds | General industrial piping with standard clearances |
| Sealing Performance | Same bubble-tight floating ball design | Same bubble-tight floating ball design |
A shortened body houses the same floating ball, seat, and stem arrangement found on standard-length valves.
Dimensional accuracy is checked closely on the compact body to confirm it meets the reduced face-to-face specification without sacrificing sealing performance.
A reduced-depth ISO 5211 pad accepts compact pneumatic or electric actuators sized for tight enclosures.
| Operation Type | Best Suited For | Key Characteristics |
| Manual Lever | Panel and skid installations with hand access | Lowest cost, minimal added depth |
| Compact Pneumatic Actuator | Automated, space-constrained manifolds | Low-profile actuator sized to match the compact body |
| Compact Electric Actuator | Remote-controlled panel or skid valves | Reduced-depth housing for tight enclosures |
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 bulk orders, air freight for urgent shipments, and express courier for samples. Compact valves are cartoned in higher density per pallet than standard-length equivalents.
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.
