Products Description
SND pneumatic 3‑piece threaded ball valve combines high‑performance aluminum pneumatic actuator and robust stainless steel three‑piece ball valve body. This automated on‑off valve is engineered for rapid remote flow control of liquid, gas and steam media. Thread end connection delivers fast and reliable installation. Widely deployed in chemical processing, water treatment, oil & gas, food‑beverage, pharmaceutical and general industrial pipeline systems. Complete assembly includes pneumatic actuator, solenoid valve, mounting bracket and valve body for plug‑and‑play field installation.
Key Features
3‑Piece Split Body Design
Easy inline maintenance without removing full valve from pipeline; quick access for internal inspection, seal replacement and repair, greatly cut down system downtime.
01
Full Port Bore
Unobstructed full‑bore flow path, minimal pressure drop, high flow capacity for fluid transmission.
02
Premium Stainless Steel Body
SS304 / SS316 stainless steel options, excellent corrosion resistance for water, weak acid, alkali, oil and gas working medium.
03
Pre‑fitted Solenoid Valve Assembly
Solenoid valve included for electrical signal control, convert electrical signal to pneumatic air signal to drive valve opening and closing. Multiple voltage choices: AC220V, AC110V, DC24V, DC12V.

Why Choose SND Pneumatic 3‑Piece Ball Valve
Complete Factory Pre‑assembly
Valve body, actuator, solenoid valve and mounting kit are fully assembled and tested before shipment. Customers directly connect air source and power supply to put into service.
Convenient On‑site Maintenance
Three‑piece split‑body construction allows disassembly and seal replacement without detaching whole valve from pipelines, lower maintenance cost.
Flexible Custom Options
Support customized material, thread standard, actuator type (spring return single‑acting), limit switch feedback, different solenoid brands and voltages.
Strong Corrosion Resistance
SS316 version works for corrosive fluid medium. Hard‑anodized actuator surface resists rust in humid workshop environment..
FAQ
Q: What is the difference between double‑acting and single‑acting pneumatic actuator?
A: Double‑acting actuator requires continuous air supply for both open and close movement. Single‑acting (spring return) will auto reset to open or close position once air pressure is lost for safety protection.
Q: Can you supply different thread standards like NPT, BSP?
A: Yes, we support NPT, BSPP, BSPT thread specifications, please specify your thread requirement while placing order.
Q: Is solenoid valve included in this valve set?
A: Yes, the whole assembly comes complete with matched solenoid valve, mounting bracket and connection parts.
Q: What temperature media can this valve handle?
A: Standard PTFE seat works ‑20℃~180℃. For higher‑temperature service, R‑PTFE seat upgrade is available.
Q: Can this valve work for salt‑water or corrosive chemical liquid?
A: Select SS316 stainless steel version for salt‑water and corrosive chemical medium for better anti‑corrosion performance.
Q: What trade terms do you accept for export orders?
A: FOB, CFR, CIF are all available. We can quote price according to your destination port.
