Size Range: 2" – 64". A trunnion mounted ball valve provides lower operational costs due to the fact that any additional pressure on the valve is absorbed by the trunnion and the stem. The most common type of ball valve has a "free floating" design, so the trunnion type is a design change. Tiger Valve Company (TVC) is a trunnion-mounted ball valve manufacturer for the TL and TB Series.
Trunnion mounted ball valves are effective in both low and high pressure situations. 5 Steel Pipe Flanges and Flanged Fittings. Tight shutoff is essential during oil and gas applications, and the superior anchoring of Forum's PBV® trunnion-mounted ball valves make them especially well-suited for large, high-pressure valve applications. However, several critical projects need to vent at a pressure less than 1. The advanced, integrated design offers numerous advantages over traditional single-isolation block valves. Materials: 316 stainless steel or Inconel nickel-chromium alloys. Our tandem valves are designed to the highest manufacturing standard including American Petroleum Institute (API) and American National Standards Institute (ANSI). The opened or closed state of the valve can be easily detected by position of the handle. View our online selection of ball valves!

In a floating ball valve, the ball is only connected to the stem, and is therefore called floating. Trunnion mounted ball valves are fitted with spring loaded seats. In one study, overlay and non-overlay valves were compared from the same worksite after six years of field service.
SP 25 Standard Marking System for Valves, Fittings, Flanges and Unions. Severe service areas can create difficult operating conditions that significantly reduce the working lifespan of oil and gas valves. Trunnion ball valve advantages.

This is advantageous since it will maintain a proper seal on both sides and there is no added torque to the stem.
In low or no-pressure situations the spring-loaded seats will create a seal, while also working for high pressure applications. NACE/fire-safe design. The fluid remains trapped within the ball, which creates a resultant pressure in the ball. Available in seat pocket, seal areas and all wetted parts. Pinion shaft extension with gear and miter box, upright orientation. Trunnion-mounted ball design feature a "trunnion" anchoring at the top and bottom of the ball. The result is the highest-quality and most competitively-priced trunnion-mounted ball valve available. Our entire valve catalog offers easy field service and numerous options such as stem extensions, locking devices, transition pieces and direct-mounted actuation. Size range: 2-24 inches. The unique design integrates double-valve functionality into a single body and creates true double block-and-bleed sealing. Learn more about ball valves in our extensive ball valve guide. After cleaning and refitting with new seals, the valves were returned to service for significant equipment savings.
