NOMINAL SIZE 6 MM ISO 4401/CETOP R35H SIZE 3
NFPA DO3 DIN 24340 A6

All ports - corner power 4500 PSI (315 BAR), 5.2 GPM /20 liters per min.

Self contained cartridges fitted in bodies with industry standard mounting interface.

Bidirectional flow capacity.

Bidirectional zero leakage closure.

With or without override.

ISO 4401 size 3 body, with or without check valve or orifice in pressure port.

Special versions with closed crossover switching characteristics for flows up to 10 liters per min. (for accumulator or clamping systems).

Coils can be replaced without disturbing or opening the hydraulic system.

(double solenoid, 4 way, 3 pos, zero leak valve)

DESCRIPTION

Series W2... poppet valves are self- contained cartridge units mounted in a body with an industry standard ISO 4401 size 3 manifold-mounting surface. They operate on the proven "guided poppet" principle and the guide stem requires only one seal. Coils can be replaced or changes to a different voltage and current (AC to DC or vise-versa) while the hydraulic system is pressurized. The 3 way / 2 position (3/2) and 4 way / 3 position (4/3) units can be supplied with poppets having closed crossover switching characteristics. These versions (all ports are isolated during valve change over) ensures no loss of pressure during switching. This is an important benefit in accumulator, low volume and clamping systems.

MDC Valves

(lever operated, 4 way, 3 pos, closed center, detented, zero leak valve)

MDC series valves are constructed of heat treated alloy steel and aluminum components. They are compact, lightweight and shift easily even under maximum pressure. The valves have extremely low leakage, less then one drop per two minutes at rated pressure.

Two working pressure ratings are available, 3000 PSI (207 BAR) and 6000 PSI (414 BAR). Temperature range is - 65F to 160F. The manifold mounting conforms to CETOP 3 mounting pattern. Mounting bolts are included with the manifold mount version. Subplates are also available

Pressure Reducing Valves

(HPA11-AX-200 w/ subplate)

A direct operated Cetop 3 pressure reducing valve is available for use with Heypac pumps that combines excellent control characteristics with very low internal leakage. The basic valves supplied in either "flange" form with a single Cetop 3 interface on the lower face for use a single sub plate mounted valve, or "sandwich" form with Cetop 3 interface on both upper and lower faces for use as part of a stack of valves. The reduced pressure is adjustable by means of a socket head screw or a hand knob.
