Rotary Lever Operated Valves

Rotary Lever Operated Valves

A range of ultra low leakage, manifold mounted rotary lever operated valves for pressures up to 414 Bar (6000 psi) and maximum flow rate 12 lpm. The valves have extremely low leakage, less than one drop per two minutes at rated pressure. They are compact, lightweight and shift easily even under maximum pressure. The manifold interface conforms to CETOP03/DO3/NG6 standards. As well as the manifold connection, the valves are also available in body-ported versions to special order. The valves are constructed of heat-treated alloy steel and aluminium components. The valves are suitable for use with mineral based oils. For use with other fluids please consult us or your local distributor.

Pressure Reducing Valves

Pressure Reducing Valves

A direct operated CETOP03/D03/NG6 pressure reducing valve for use with HEYPAC pumps. The valve is supplied in either “flange” form (HPA11) for use as a single sub-plate mounted valve or “sandwich” form (HPA12) for use as part of a valve stack. The reduced pressure is adjustable by means of a socket head screw.

  • Maximum inlet pressure 315 Bar
  • Maximum flow rate 20l/min
  • Reduced Pressure Ranges – see ordering code
