Motor-driven quarter-turn shutoff on a PVC, CPVC, PP, or PVDF ball valve body — wired on/off or modulating control for remote, unmanned, or BMS-integrated installations.
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 Electric Motorized Plastic Ball Valves Manufacturers and Custom Electric Motorized 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.

Electric motorized plastic ball valves pair a PVC, CPVC, PP, or PVDF ball valve body with an electric actuator mounted on a standard ISO 5211 pad. An internal motor and gear train rotate the valve stem 90 degrees between open and closed, giving on/off or modulating control without needing a compressed air line running to every valve — a practical advantage on sites where instrument air is limited or where valves are spread across a wide area.
The actuator accepts standard AC or DC supply voltages and typically offers on/off relay control, or 4–20 mA / 0–10V modulating control on proportional models, along with local position indication and manual override. This makes electric actuation well suited to remote or unmanned installations, building management system integration, and any application where a wired electrical signal is easier to run than compressed air.
A wired electric actuator suits installations without compressed air, or where precise, remotely monitored positioning is required.
The valve body material is chosen for chemical service, while the actuator is selected for supply voltage and control type.
| Component | Material / Spec Options | Selection Basis | Notes |
| Valve Body | PVC-U, CPVC, PP, PVDF | Matched to the process fluid and temperature | Wetted parts unchanged from manual valve |
| Actuator Housing | Die-cast aluminum, IP67-rated enclosure | Indoor or outdoor duty, wash-down exposure | Weatherproof gasketed cover as standard |
| Supply Voltage | AC100–240V or DC12/24V | Site electrical infrastructure | On/off or modulating models available |
| Manual Override | Hand-wheel or declutch lever | Emergency operation on power loss | Standard on most actuator models |
| Item | Description |
| Valve Type | Electrically actuated two-way plastic ball valve |
| Body Material | PVC-U, CPVC, PP, or PVDF |
| Seat / Seal Material | PTFE seats; EPDM or FPM seals |
| Size Range | DN15 – DN100 (1/2 inch – 4 inch) |
| End Connection | Socket, threaded, or flanged |
| Working Pressure (valve) | Up to 230 psi (16 bar) at 20°C, material dependent |
| Working Temperature | -10°C to 99°C, material dependent |
| Control Type | On/off (2-position) or modulating (4–20 mA / 0–10V) |
| Supply Voltage | AC100–240V or DC12/24V, model dependent |
| Enclosure Rating | IP67 as standard |
| Mounting Standard | ISO 5211 direct mount |
| Optional Accessories | Position feedback, manual override, local control switches |
Both automate the same valve body; the choice generally depends on whether the site already runs electrical wiring or compressed air.
| Factor | Electric Actuated Valve | Pneumatic Actuated Valve |
| Power Source | Electrical supply (AC or DC) | Compressed air |
| Infrastructure Needed | Electrical wiring and control cabling to each valve | Compressed air distribution to each valve |
| Modulating Control | Widely available with proportional actuator models | Possible but less common, needs a positioner |
| Cycle Speed | Generally slower, smoother travel | Very fast, typically under a few seconds |
| Remote Sites | Practical where power is available but air lines are not | Requires a compressed air line to the valve |
| Fail-Safe on Power Loss | Needs battery backup or manual override | Spring-return actuators fail safe automatically |
An electric actuator bolts onto the valve's ISO 5211 pad, with an internal motor and gear train rotating the stem.
Inspection covers both the valve body and the actuator's wired cycling and control response before shipping as a matched assembly.
Actuator torque must exceed the valve's break-to-open and running torque, and control type is selected to match the upstream control system.
| Control Type | Best Suited For | Key Characteristics |
| On/Off (2-Position) | Simple remote shutoff and isolation points | Relay-driven open/closed control, position feedback contacts |
| Modulating (4–20 mA / 0–10V) | Flow throttling and process control loops | Proportional positioning driven by an analog control signal |
| Manual Override | Emergency or maintenance operation | Hand-wheel or declutch lever engages when power is unavailable |
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 of matched valve-actuator assemblies.
Shipping: Sea freight (FCL/LCL) for bulk orders, air freight for time-sensitive automation projects, and courier for samples. Assemblies ship pre-mounted and tested in wooden crates.
Delivery: Shipment from the nearest available port or airport, with door-to-door, FOB, CIF, or EXW terms on request.
Each assembly is covered under a standard warranty against manufacturing defects in material and workmanship, generally valid for 12 months from the shipment date, covering both valve and actuator.
