Keystone K-LOK 36 & 37 Butterfly Valve
The Keystone K-LOK 36 and K-LOK 37 are high performance Butterfly Valves.
The Keystone K-LOK 36 and K-LOK 37 are high performance Butterfly Valves. The Keystone K-LOK 36 and 37 can be used for airport refueling, hydrocarbon processing, and chemical and petrochemical processing.
K-LOK polymer and elastomer seats provide bi-directional, drop-tight shut-off in vacuum as well as at full rated differential pressure. Its unique design does not rely on pressure to assist sealing therefore seals at high and low pressures, as well as dirty services. A variety of materials allows optimum seat life in all applications.
Features
Blow-out resistant shaft is standard on all valves for increased safety
Unique packing design allows for use in pressure as well as vacuum without modification or special assembly
Disc taper pins are tangentially positioned half in disc and half in shaft, placing them in compression rather than shear, which eliminates potential for failure
Rocker-shaped gland bridge compensates for uneven adjustment of gland nuts reducing packing leaks
Integrally cast disc position stop perfectly locates the disc in seat, achieving maximum seat and seal life
Extended neck allows for two inches of pipeline insulation
Integrally cast mounting pad provides direct mounting of actuators eliminating the need for costly brackets and couplings
Flattened body bore at shaft journal ports positions shaft bearings near disc, providing maximum shaft support resulting in reduced wear and longer life
