On the other hand, we adopt a new testing methodology for producing superior products over the years. From 2015 to now, we stand and bagged appreciation through our craftsmanship. This farm has become more capable than before by producing customizable products to suit the trade. We are trustworthy a Trunnion Mounted Ball Valve manufacturer. However, our world-class products are the benchmark of our high-pressure valve.
For instance, we have brought Trunnion Mounted Ball Valve for our reliable customers and potential customers. They can get various designs with fine line finishing. Trunnion Mounted Ball Valve is a quarter-turn ball valve. It is used for starting or stopping media flow in a pipe. Free-floating design is the common type of ball valve design. We can change the design of the Trunnion Mounted Ball Valve as per the client’s demand.
In general, the word Trunnion is obtained from the old French word “trunk”. On the other hand, Trunnion is placed into a partial or full cylinder to craft the bearing. This valve helps to rotate and join the part to pivot if needed. With the help of the top shaft and bottom shaft, a Trunnion ball is connected inner part of the valve. In other words, a floating ball is centred via a valve stem.
Special Features
Bolted Body Construction
- As a standard, the valves are manufactured in 2-piece or 3 Piece bolted body designs, where the joint between the body and the connector is bolted.
Double Block and Bleed
- Sunvalvess Trunnion Mounted Ball Valves are designed for upstream sealing, so that the double block and bleed features are automatically built in. The load generated by the line fluid on ball is absorbed by the Trunnion bearings and is directly transmitted to the valve body.
- The valve stem is hence free from any bending load which leads to reduced stem friction torque and enhanced stem seal life. The seat rings are allowed to float in the flow axis against a fixed ball so that the line pressure assists in pressing the spring-loaded upstream seat against the ball. Thus, the operating torque and wear on the seats is relatively low, enhancing seat life.
- The seats provide the positive seal at both upstream and downstream independently. The fluid is blocked from the body cavity; this facilitates to check the integrity of the upstream and downstream seats.
How does it work?
The trunnion is an accurate ground-bearing fixture that grants to mount to the surface. Typically, it will support full rotation of the fixture and parts attached to it. This valve provides a lower operational cost.
On the other hand, the Trunnion Mounted ball valve floats against the seat ring. This valve builds sealing on valve one side. A Trunnion ball valve or V port ball valve is the best-suited valve for flow control applications in industrial sectors.
Structure:
In other words, there are several structures of Trunnion Mounted ball valves. These are – ball, seat, body, stem, injection, and Trunnion.
The ball has sphere shape disk and it moves rotationally. The ball has been made through multiple materials like stainless steel, super duplex, duplex, Inconel, and carbon steel. Seats are encircled by the ball. If the actuator is turned on, the seats retain the ball in a solid place. To prevent leakage, grease may be injected through sealant injection fitting.
On the other hand, it acts to stop further leakage as a partial seal. The stem controls the ball movement and it can handle intense temperatures without any kind of leakage. From beneath, this Trunnion ball valve captures the ball positions via an extra shaft.
Advantages :-
-
- Trunnion mounted ball valve decreases the defect of casting design.
- Easy to install for various places.
- On the other hand, this valve is convenient to construct and repair.
