Description

• 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.
• 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 50 mm (2″) 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.
