Keystone K-LOK® High Performance Butterfly Valve Sizes 50mm–900mm ANSI Class 150 and 300
Features & Benefits:
Integrally cast mounting pad provides direct mounting of Keystone F79U pneumatic actuators.
Rocker-shaped gland bridge compensates for uneven adjustment of gland nuts.
Extended neck allows for 50mm of pipeline insulation.
Flattened body bore positions stem bearings near disc, providing maximum stem support.
Disc taper pins are tangentially positioned half in disc and half in stem, placing them in compression rather than shear, which eliminate potential for failure.
Integrally cast disc position stop perfectly locates the disc in seat, achieving maximum seat and seal life.
Uninterrupted flange face retaining ring allows use of standard spiral wound gaskets.
K-LOK polymer seats incorporate a true interference seat design that does not rely on line pressure to assist sealing. This design provides bi-directional, drop-tight closure in vacuum and throughout all pressure ranges, as well as at full rated differential pressure. A variety of materials allows optimum seat life in all applications.

The Keystone K-LOK valve is designed for a wide range of applications such as:
Process Control
Food Processing
Sour Gas
Oxygen Service
Reverse Osmosis
Category ‘M’ Fluids
Light Slurries
