SR06-01
Flow Regulator, Pressure Compensated, Restrictive Type
Up to 4 gpm (15 l/min) • 5000 psi (350 bar)

Description
A screw-in cartridge, adjustable, pressure compensated, hydraulic flow regulating valve (restrictive type).

Operation
The SR06-01 maintains a constant flow from port 1 to port 2 based on the setting adjustment, regardless of pressure changes downstream of port 2. The flow rate is determined by a fixed control orifice and could be adjusted within a limited range. Reverse flow from port 2 to port 1 is at the value of the fixed control orifice and is non-pressure compensated.

Features

  • Excellent stability throughout flow range
  • Desired setting may be locked down
  • Adjustment screw cannot be backed out of the valve
  • All external surfaces zinc-plated
  • Hardened parts to ensure minimal wear and extend service life

SRP08-01
Flow Regulator, Pressure Compensated, Priority Type
Up to 8 gpm (30 l/min) • 5000 psi (350 bar)

Description
A screw-in cartridge, adjustable, pressure compensated, priority type hydraulic flow regulating valve.

Operation
The SRP08-01 maintains a constant priority flow from port 1 to port 3 based on the setting adjustment, regardless of pressure changes downstream of port 3 or in the bypass line at port 2. The flow rate is determined by a fixed control orifice and could be adjusted within a limited range. Flow in excess of the priority setting is directed to port 2. If the priority flow at port 3 is blocked, the spool will shift, thereby closing off flow to port 2.

Features

  • Excellent stability throughout flow range
  • Reverse flow capability
  • Desired setting may be locked down
  • Adjustment screw cannot be backed out of the valve
  • Bypass port 2 may be fully pressurized
  • All external surfaces zinc-plated

 ST10-01-1.jpg

ST10-01
Flow Divider/Combiner, Spool Type
Up to 12 gpm (45 l/min) • 5000 psi (350 bar)

Description
A screw-in cartridge, spool type, pressure compensated flow divider/combiner.

Operation
In the dividing mode, ST10-01 divides the input flow on port 3 between ports 2 and 4, based on the specified ratio, regardless of the operating pressure. In the combining mode, the flow from ports 2 and 4 will be combined into port 3. The division or combining will be maintained even if unequal loads are placed on ports 2 and 4.
The ST10-01 provides synchronizing flow in both combining and dividing modes at bottomed conditions in cylinder applications and at stalled conditions in motor applications. This feature is useful in hydraulic circuits that require cylinders to move at the same time. If one cylinder bottoms out first, the opposite cylinder is provided with a synchronizing flow to allow that cylinder to bottom before both cylinders start moving in the opposite direction.

Features

  • All external surfaces zinc-plated
  • Hardened parts to ensure minimal wear and extend service life
  • One piece body maximizes reliability and minimizes the effects of eccentricity
  • High accuracy operation
  • Wide flow range down to 25% of nominal flow rating
  • Low pressure drop
  • Provides re-synchronizing flow after completion of the actuator cycle
  • Industry common cavity
