High Pressure Lateral Valves

The lateral high-pressure valves are valves with two or three connections and two switching positions. The pressure range extends from vacuum up to 500 bar. In this type of construction, the valve drive is not arranged coaxially, but laterally.

Depending on the type, the high-pressure valves are available with either a magnetic actuator or with a pneumatic/hydraulic actuator. The nominal width ranges from 1.5 to 15 mm, the bandwidth of the flow factor (KV value) from a few liters to 3.5 m³/h.

The pneumatically operated valves of the PCD series in particular have an exceptionally positive relationship between high pressure range and high flow rate due to their high switching force. Thanks to their unique coaxial construction, the valves of the PCD10 and PCD15 series already respond from 3 bar control air pressure, whereby the air consumption per stroke is sometimes only 1/10 of the value of well-known competitors. By using the coax valves, the consumption of expensive compressor air is significantly minimized. This makes these valves particularly energy-efficient. Due to the high switching force, the externally controlled valves can optionally be equipped with dirt wipers. They are also ideally suited for use with abrasive media in the high-pressure area.

With the fine throttles on the pilot valves, the user can set the switching times as desired. Switching delays of up to three seconds when opening and closing are possible. This allows hydraulic pressure surges in piping systems to be prevented.

This series is typically used in gas filling stations and test benches, in compressor and hydraulic systems and in washing machines up to a maximum pressure of 500 bar.


The valves can be optionally equipped e.g. with alternative pilot valves, limit switches, mounting brackets, with various plug connections such as M12x1 DESINA/VDMA, or with special PWM plugs for current reduction.
