Características

Keystone K-LOK® Series 36/37 High Performance Butterfly Valve
  • K-LOK polymer and elastomer seats provide bi-directional, drop-tight shut-off in vacuum as well as at full rated differential pressure.
  • 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.

  • Direct mounting to all Keystone butterfly valves and ball valves.
  • Valve connection compatible with Keystone (imperial and metric) and ISO 5211.
  • Double Rack and Pinion design nullifies side loads on the pinion shaft, minimizing bearing wear and extending life.
  • Optimized product flow with standard mounted travel stops for valve position adjustment in open and close position (+/- 5° at each end).
  • Anodized aluminium body with electrostatic powder coating (ESPC) finish provides durable protection against corrosive environments.
  • Double acting and spring return versions available for cost effective and safe operation.
  • Up to 12 individual springs offer flexible torque range for both ball as butterfly valves.
  • Pre-compressed spring design and anti-blowout drive pinion means safe maintenance and operation.

  • Montagem direta para todas as válvulas borboleta e válvulas esféricas Keystone.
  • Conexão de válvula compatível com Keystone (imperial e métrico) e ISO 5211
  • O design de pino e cremalheira duplo anula os carregamentos laterais no eixo do pino, minimizando o desgaste do rolamento e aumentando a vida útil.
  • Caudal de produto otimizado com fins de curso padrão montados para ajuste da posição da válvula nas posições aberta e fechada (+/- 5� em cada extremidade).
  • O corpo em alumínio anodizado com revestimento eletrostático em pó (ESPC) fornece proteção durável contra ambientes corrosivos.
  • Versões de dupla ação e de retorno por mola disponíveis para operação segura e económica.
  • Até 12 molas individuais oferecem flexibilidade no alcance do torque tanto para válvulas esféricas quanto para borboleta.
  • O design de mola pré-comprimida e pino de acionamento à prova de rompimento significam manutenção e operação seguras.
