Directly controlled and pneumatically actuated pressure control valves provide continous, stepless pressure regulation. Adjustment time between pressure settings is less than one second. Regulated pressure remains constant regardless of system conditions. Pneumatically actuated pressure control valves are adjusted by either proportional control valve (requires 0 - 10 V control signal) or manually. Complete isolation of the control section from the media makes them insensitive to dirt. (read more)Browse Control Valves Datasheets for co-ax valves inc. -
Pressure reducing valves used in a hydraulic circuit require maintaining a constant outlet pressure despite a higher and changing inlet pressure. These valves are commonly used when a secondary circuit has to be fed with a lower but constant pressure level by a primary circuit with a higher and varying pressure level. The direction of flow can be reversed with up to 2 x Qmax. Other conventional pressure reducing valves require a leakage port, the CDK prevents leakage when closed and therefore...

With this valve, the drop rate of forklifts and lifting platforms remains the same at constant volume flow regardless of the load. Due to the cone seated design, the valve is zero-leackage in closed position and so maintains pressure reliably. This facilitates manufacturers compliance with the standard ISO 3691.1. The constant, load-neutral volume flow makes for operator-friendly hydraulic control systems using joysticks. The operator can precisely estimate the drop rate according...

The function of this valve is to automatically maintain a constant pressure-differential at varying rates of flow. When the valve discharges to atmospheric pressure it functions as a spill valve, maintaining a constant upstream pressure. When the valve discharges to a system containing restrictions, orifices, seal or bearing clearances, it serves as a pressure regulating valve, maintaining a constant differential between upstream and downstream pressures regardless of flow. Two or more valves... (read more)Browse Check Valves Datasheets for Tate Andale

Pressure Valves
flow-control valves could be used to control pressure. If orifice size, supply flow, and fluid viscosity are fixed, pressure remains constant; if any one of the three varies, pressure varies. Typically, however, such valves produce only the crudest kind of pressure control. For more accurate control, several
