Valbart designed the Trunnion Mounted Control Ball Valve (TMCBV) to operate at high pressures while minimizing the torque needed to operate the valve. The spring-loaded, process energized seats offer tight (Class IV and Class V) shutoff at any pressure. In most cases, the TMCBV's capacity is greater than that of a comparable globe valve. This allows the customer to use a smaller, lighter valve and experience cascading savings. This valve also requires a smaller, less expensive actuator and less expensive pipe supports.
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:
