The TrunTech® design is a lightweight, high-pressure valve design that meets API 6A/6D requirements. The valve offers low torque operation, high-pressure sealing, and resistance to solids contamination. The TrunTech® design meets stringent emission requirements and provides long life in abrasive and erosive conditions.
The body is the primary pressure boundary and requires zero maintenance. The three piece design of the TrunTech® means that the same body can be used for multiple types of end connections. Weight reduction is also achieved by removing unnecessary material as compared to a traditional two piece design. Injection fittings allow for additional sealing capability.
The bonnet holds the stem within the valve under high pressure and also houses the stem packing and bonnet seals. The bonnet also features an injection fitting for additional sealing capability.
Provide additional stability and support during shipping, installation, and operation.
High pressure seals that can be composed of various compounds for chemical and temperature compatibility. O-rings are installed in precision machined grooves to allow for a durable, versatile, high pressure seal.
The hardened stem is contained by the bonnet and features a blowout proof ring. Stem is designed to exceed the maximum torque of the actuator, ensuring the stem will not break under high stress applications.
Allows the seats to “float” on the ball and seal to a bubble tight shutoff. Also contains o-rings to prevent leakage around the outside of the ball.
The ball is coated and diamond lapped to ensure bubble tight shutoff. The coating is designed to reduce wear and increase the life of the internal valve components.
End Cap Front
Multiple endcap configurations are available, and all of them can bolt to the same valve body. This offers versatility along with reduced costs. Weight reduction is achieved by removing unnecessary material as compared to a traditional two piece design. The endcap can also feature injection fittings for additional sealing capability.
Center the ball within the valve to ensure concentric cycling of the ball.
Reduces wear and galling of the trunnion components. Ensures smooth cycling of the valve during operation.
