Hydraulic check valve Holmbury

INTRODUCTION
One-way valve for in-line use.
Suitable for any type of hydraulic system using
liquids that are not highly viscous. The standard
types are in zinc plated carbon steel and are
therefore especially suitable for non-corrosive mineral
based oils and liquids.
FEATURES
Standard types: Good pressure / flow characteristics, see graphs. Valve body in zinc plated carbon steel. Piston in carbon steel. Internal spring in silicon steel - stabilized. Cracking points 5 psi and 65 psi are standard,
other values on request.
ALTERNATIVE USES
As a pressure sequence valve by changing the
internal spring to an appropriate 'cracking point' value.
For flow restrictor check valves a central bleed hole
can be provided, sized to customer requirements.
