Modular Pilot-Operated Check Valve MPW Series
MPW-03 series modular pilot-operated check valve that holds a load until pilot pressure opens it, mounted between directional valve and subplate....
Product Overview
This valve is the MPW-03 modular pilot-operated check valve. It blocks reverse flow until pilot pressure acts on the piston, so a cylinder holds position without drifting when the valve centres.
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
Confirm nominal size, cracking pressure and pilot ratio; the pilot line must be able to open the valve at the expected load pressure.
Applications
Load holding on press circuits, clamping fixtures and vertical cylinders.
Frequently Asked Questions
Load drifts down slowly when the valve centres
Check pilot line sealing and spool wear; internal leakage in the pilot check allows gradual drift.
