Product Details
Product Overview
This item is the MSW-04 modular one-way throttle valve. Flow is throttled in one direction and passes freely in reverse, giving adjustable speed in one movement of the actuator.
Structure and Key Features
- Modular or subplate body with ports arranged to common mounting standards.
- Spools are matched and lapped, keeping internal leakage low when closed.
- Adjustment is lockable so the setting does not drift.
Specifications and Selection
Set the throttle by flow requirement rather than by feel, and check that minimum settable flow suits the slowest required speed.
Applications
Cylinder speed control on machine tools, clamps and test stands.
Frequently Asked Questions
Speed changes as oil temperature rises
Throttle control is sensitive to viscosity; use pressure compensation or a flow control valve where speed must stay constant.
