Needle Valve, Spool Type, Metric Cartridge – SDH05330

Needle Valve, Spool Type, Metric Cartridge, SDH05330

The SDH05330 is a hydraulically operated, spring-loaded, adjustable spool valve.

In the normal position, the valve is open and there is flow from port 3 to port 2. When we apply control pressure to port 1, the valve switches into the flow control position and it reduces the flow.
Adjustment of the flow setting is possible by using the set screw (clockwise to increase flow, counter-clockwise to decrease flow).

Caution: the control pressure must generally be greater than the pressure at port 2, otherwise the valve will not function. In order that the valve switches back from the flow control position to the fully open position, we must vent port 1 and (at this moment) there must be no flow through the valve.

See datasheet for drawings, dimensions, model code, etc…

Features:

  • Flow control is dependent on the viscosity of the oil and the system pressure
  • A lock-nut lock the setting
  • External surfaces zinc-plated
  • Hardened and ground control piston to ensure minimal wear and extended service life
  • Compact design
