High Performance Butterfly Control Valves About this product
The Valtek TX3 butterfly valve offers excellent shutoff capabilities with the low torque and reduced wear benefits of a triple offset design. The precision seat and seal are machined at an offset angle, creating even seat loading around the entire seat ring and eliminating rubbing between the seat and seal during opening and throttling. Combined with its laminated seal ring, the Valtek TX3 valve's triple offset design provides long-lasting, bi-directional, bubble-tight shutoff, even in gas applications.
It's high-performance design offers the following advantages:
- Higher reliability -- API 598 zero-leakage shutoff assured by triple offset design and laminated metal graphite seat seal
- Extended service life -- owing to low-operating torque resulting from the low-friction, low-wear elliptical sealing surfaces
- Minimized emissions -- packing options meet stringent fugitive emissions (ISO 15848-1) requirements
- Improved safety -- API 607 fire-safe design plus API 609 anti-blowout shaft
Safety Standards

Fugitive Emission
ISO 15848
- Laminated graphite or metal-to-metal sealing provides reliable, long-lasting zero leakage (API 598) shutoff, even in gas applications
- Triple offset design eliminates wear associated with sealing surface contact and maintains sealing integrity during high cycle operation
- Robust, anti-blowout shaft meets requirements of API 609
- Low-operating torque for compact, cost-effective actuation
- Meets industry standards for design, fire safety and fugitive emissions
- Combined with a high-thrust actuator, the Valtek TX3 achieves high performance throttling control in a wide range of industry applications
- The smart positioner makes sure the valve is always in the right, exact position to optimize process parameters and provide operators with the information they need
