Fig. 8910 and Fig. 8950 Throttle Trip Valves provide effective flow control and emergency shut-off operation in a single, highly reliable valve assembly. As throttle valves, they are used to regulate flow of steam and gas in large, high-pressure pipe lines, such as the main steam line serving a large, high-pressure turbine or a turboexpander gas supply line. As trip valves, they add a measure of safety critical to these applications, without the expense of a separate trip valve. When tripped either manually or automatically, the valves rapidly shut down flow to protect valuable equipment.

S&K throttle trip valves are available in a variety of configurations for suitability to your application requirements. In addition, they can be manufactured with soft packing, hardened leak-off bushings, and various materials for critical applications. Complete physical testing offered by S&K includes hydrostatic and pneumatic testing as well as magnetic particle (magnaflux) and radiographic (xray) inspection. All models are ANSI rated.
