For industrial pipelines where valve stability, reliable isolation and controlled operating torque matter, a trunnion mounted ball valve can be an important part of the flow control system.
Ultra Valves Automation Pvt. Ltd. welcomes enquiries for trunnion mounted ball valves from industrial buyers in Mumbai and across India. Explore the valve construction, working principle, material options and technical specifications below.
A trunnion mounted ball valve uses mechanical supports to hold the ball in position while it rotates between open and closed states. Unlike a floating ball design, the ball is supported so that it does not move freely against the downstream seat under line pressure.
In a typical trunnion mounted ball valve design, the seat arrangement moves towards the ball to establish sealing contact. This construction is often considered for larger valve sizes and demanding pressure conditions, subject to the actual valve design and rating.
Whether you're comparing trunnion mounted ball valve manufacturers or reviewing a mounted ball valve for an industrial project, the important starting points are the pressure class, body material, seat design, valve size and operating conditions.
Understanding the construction and operating characteristics helps buyers select a suitable valve for their pipeline.
Mechanical support helps hold the ball in position during operation, reducing the load transferred to the seats compared with a floating ball arrangement.
A 90-degree rotation moves the ball between fully open and closed positions for pipeline isolation.
A 2 piece trunnion mounted ball valve can use a two-section body construction. The exact assembly and maintenance arrangement depends on the model.
Stainless steel material grades are listed among the supplied body, ball and stem options for suitable applications.
PTFE and PFA seating options are listed. The selected material must be compatible with the operating conditions.
Handle, gear, electric and pneumatic operation options allow buyers to discuss different control arrangements.
The following material grades and configuration details are reproduced from the supplied product specification.
| Component / Specification | Product Details |
|---|---|
| Body / Connector | CI IS210 GR FG220 / CS ASTM A216 Gr. WCB / ASTM A351 CF8 / ASTM A351 CF8M + PFA / FEP Liner |
| Ball | ASTM A351 CF8 / CF8M |
| Seat | PTFE / PFA |
| Stem | 410 / 304 / 316 |
| Gland Packing / Gland Bush | PTFE |
| Gland Bolts | SS304 / C.S. / High Tensile |
| Sizes | ½″ (15 NB) to 8″ (200 NB) |
| Pressure Class | ANSI Class 150 / PN10 / PN16 |
| Valve Body Design | ASME B16.34 – 2 Piece Design |
| Flanged Drilled | Flange ASME B16.5 Class 150 RF / DIN Standard / PN10 / PN16 / PN40 |
| Operation | Handle / Gear Operation / Electric or Pneumatic Operation |
Technical note: The above details were supplied for this page and require verification against the actual trunnion mounted ball valve datasheet. In particular, confirm the trunnion support construction, PFA/FEP lining applicability, pressure ratings, valve sizes and body design. PN40 flange drilling does not establish a PN40 valve pressure rating.
The key difference is the supported ball construction and the way the seats establish sealing contact.
The bore through the ball aligns with the pipeline, allowing the process fluid to flow through the valve.
Rotating the stem by 90 degrees moves the solid surface of the ball across the flow passage to stop flow.
The trunnion support holds the ball in position. Depending on the design, the seats are urged towards the ball to establish sealing contact.
A trunnion mounted ball valve is commonly selected for on-off isolation. Pressure rating, seat construction, operating torque and material compatibility must be confirmed for the intended process.
A 2 piece trunnion mounted ball valve has a body assembled from two main sections. The arrangement of the body joint, supports, seats and sealing components depends on the manufacturer and model.
The trunnion mounted ball is mechanically supported rather than relying on line pressure to move the entire ball against the downstream seat.
Buyers evaluating a customized trunnion mounted ball valve should confirm the required body construction, seat arrangement, pressure class, materials, flange connections and actuator requirements.
A stainless steel trunnion ball valve may be considered where the process requires suitable corrosion resistance and material compatibility. However, stainless steel grades are not interchangeable for every chemical or operating condition.
The supplied specifications include ASTM A351 CF8 and CF8M for the ball, with 410, 304 and 316 stem material options. Stainless steel body grades are also listed.
Before selecting a stainless steel configuration, review the process fluid, temperature, pressure, required corrosion resistance and the applicable valve design.
Industrial buyers in Mumbai often need valves that match detailed piping specifications. Choosing a trunnion mounted ball valve involves more than selecting a nominal size or pressure class.

Answers to common questions about valve design, materials, operation and industrial product enquiries.
A trunnion mounted ball valve is a quarter-turn isolation valve in which the ball is supported by a mechanical trunnion arrangement. The supported ball rotates to open or close the flow passage.
The ball rotates by 90 degrees between open and closed positions. Mechanical supports hold the ball in position while the seat arrangement provides sealing contact.
A two-piece design uses two main body sections assembled together. The exact support, seat and maintenance arrangement depends on the valve model.
A floating ball valve allows limited movement of the ball under line pressure. A trunnion mounted valve mechanically supports the ball and typically uses movable seat arrangements to establish sealing.
Stainless steel material options are included in the supplied specifications. The exact body, ball and stem combination should be confirmed for the required valve model.
Custom configuration requirements can be discussed by providing a detailed datasheet. Feasibility depends on the required size, materials, pressure class and design.
Electric and pneumatic operation are listed among the supplied operating options, along with handle and gear operation. Confirm actuator compatibility for the selected model.
The supplied specification lists sizes from ½ inch (15 NB) to 8 inches (200 NB). This range should be verified against the actual trunnion mounted valve datasheet.
