Product Details
Product Overview
This valve is the MHB-03 modular counterbalance valve, the type marked on the product image. A check valve allows free flow in one direction; in reverse the valve opens only when pilot pressure overcomes the spring setting.
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 valve slightly above the load-induced pressure to prevent creep, and confirm the pilot ratio suits the cylinder area ratio.
Applications
Vertical cylinders, lift tables and press rams that must not fall when the pump stops.
Frequently Asked Questions
Load creeps down when the pump stops
Setting is below the load pressure or the seat is contaminated; clean the seat and reset above the holding pressure.
