Product Description

Pneumatic Forged Steel Trunnion Mounted Ball Valve

Pneumatic Actuated ball valve is designed with an upper and lower stem fixed valve core (shaft supported) and a movable sealing seat. More stable work. Equipped with automatic compensation function, bi-directional sealed valve seats have great shear force and self-cleaning function when rotating without gap between them.

For the full bore valve, the bore diameter i.e hole in the ball has the same internal diameter as the pipe, whereas a reduced bore valve has a smaller bore diameter than the internal diameter of the pipework it is on. Full-port ball valves are used where their low flow resistance is of value such as on pump suction pipes, where a pressure drop can affect pump performance.

Product Features

⚙️

1. Pneumatic Actuation:

Allows for precise, automatic control of fluid flow, reducing the need for manual intervention and improving system automation.

✂️

2. Shear Force Resistance:

The V-incision metal seat design allows the valve to handle fiber and small solid particles, such as pulp, without compromising sealing performance.

🎯

3. Precise Flow Control:

Provides precise regulation and reliable positioning, with roughly equal percentage flow characteristics and an impressive 100:1 adjustable ratio.

Frequently Asked Questions

Q1: What is the advantage of a trunnion-mounted design? A: The trunnion-mounted design uses an upper and lower stem to fix the valve core, providing greater stability and a more reliable seal under high-pressure conditions compared to floating ball valves.

Q2: Can this valve handle media with solid particles? A: Yes, the V-incision metal seat design provides a shear force that can handle fibers and small solid particles like pulp, maintaining a clean sealing surface.

Q3: What is the difference between hard and soft seals? A: Soft seals (like PTFE) offer excellent bubble-tight shutoff at lower temperatures (up to 180ºC), while hard seals are designed for higher temperature applications (up to 300ºC).

Q4: How does pneumatic actuation improve system performance? A: It allows for automated remote control, faster response times, and precise positioning, which is critical for industrial automation and flow regulation.

Q5: What body materials are available for corrosive environments? A: We offer stainless steel options such as CF8, CF8M, and CF3M, which provide excellent resistance to corrosion in various chemical and industrial applications.
