1 Inch Pneumatic Ball Valve Full-Port For General Industrial Pipeline Control
1″ pneumatic ball valve with full-port design, for water circulation, pneumatic circuits and skid-mounted industrial equipment.
Description
1. Product Overview
The 1″ pneumatic ball valve (DN25) is a general‑purpose, small‑to‑medium bore pneumatic valve that uses compressed air to drive a pneumatic actuator, rotating the ball 90° for on/off flow control. It is available with a full‑port (full‑bore) design, where the ball opening matches the nominal pipe diameter, ensuring minimal flow resistance and maintaining high throughput.
Actuators come in double‑acting and single‑acting spring‑return types; the latter automatically closes upon air supply failure. Optional accessories such as solenoid valves and limit switches allow integration with PLC automation systems. With BSP/NPT threaded or flanged connections, the valve offers flexible installation. It is widely used in HVAC circulating water, water treatment, small skid‑mounted equipment, factory air‑supply lines, and other general industrial fluid applications.

4. Real‑World Project
At the Hvac‑Sys Vienna HVAC project in Vienna, Austria, the 1″ pneumatic ball valve was installed in bulk on circulating water lines. The full‑bore configuration effectively lowers system pressure drop, ensuring stable high‑flow delivery for the HVAC automation system. For routine circulating‑line duties, the double‑acting 1″ pneumatic ball valve is selected for standard on‑off control.
5. Selection Guide & Distinctive Strengths
The key advantage is its full‑bore design – the unconstricted ball provides ample flow area with low pressure loss, avoiding flow bottlenecks and meeting the high‑capacity demands of small‑to‑medium piping. The 1‑inch size is an industry‑standard diameter, offering broad compatibility with off‑the‑shelf pipe fittings, simplifying procurement and on‑site installation.
-
For fail‑safe closure upon air supply failure → choose the spring‑return 1″ pneumatic ball valve.
-
For corrosive media → prefer the stainless steel 1″ pneumatic ball valve.
-
For central control needing position feedback → configure with the limit switch 1″ pneumatic ball valve.
Note: Full‑port balls require higher actuation torque – verify actuator sizing during selection. Installing a strainer upstream is recommended to prevent debris from scoring the ball sealing surfaces. The product complies with CE industrial standards. We provide dimensional drawings, torque selection tables, and installation/maintenance manuals to facilitate system design and project acceptance for overseas engineering contractors. Bulk orders are welcome, and actuators and seals can be supplied separately to shorten spare‑parts lead times and reduce equipment downtime.
