Keystone Introduces New Extended-Service Butterfly Valve—Literature Offered

Keystone Valve-USA of Houston, Texas, recently announced the availability of a new line of butterfly valves for high-pressure/ high-temperature services.

Literature is offered detailing the K-LOK valve's capability of handling line pressures up to 740 psi and temperatures up to 1,100 degrees F. The valve design incorporates a high-capacity, Equalinear disc, providing maximum flow area, and superior flow characteristics.

Unique seat design allows bidirectional flow and shut-off regardless of line pressure, in TFE, RTFE, UHMWPE, and metal configurations.

Actuators may be flush-mounted, eliminating the need for costly mounting brackets and adapters. Stem packing is fully and readily adjustable without having to remove the directly mounted actuator. Packing design combines braided TFE with solid TFE "V"-rings for a superior stem seal under pressure or vacuum.

Available in wafer and lug s t y l e c o n f i g u r a t i o n s 2y2-inch through 24-inch, the K-LOK valve is designed in full compliance with ANSI, API, and MSS standards where applicable, as well as comparable international standards.
