Pilot valves

High-pressure pilot-operated stop valves
LB Bentley’s pilot-operated stop valve was developed for use on our high pressure desiccant dryers, to initially fulfil a specific MOD requirement. The compact cartridge design is ideal for manifold applications and enables the company to supply an extremely compact, automatic dryer designed for ship use.

We have standardised this valve throughout our industrial dryer range as it offers exceptional reliability and is quick and easy to service.

This unique patented design is ideal for high pressure compressed air or gas and hydraulics applications and is available as a standalone valve or as a cartridge design for manifold use.


Manual valves

Manual stop valves
LB Bentley’s manual stop valves are manufactured in 316 stainless steel as standard (other materials are available) and are suitable for high-pressure compressed air and other inert gases to 414 bar having 1/4″ BSPP connections.

It is a simple, manually-operated valve, the seal of which can be replaced without taking the body out of line. For non-inert gases please contact us direct.



Coaxial breakaway couplings
LB Bentley’s coaxial breakaway couplings are suitable for high pressure compressed air and other inert gases to up to 450 bar. They are manufactured from CZ121 Brass and Phosphor Bronze. Sealing of the couplings is achieved by O-rings.

The breakaway couplings allow items, such as valves, to be removed without having to ‘spring’ the pipework, making service work considerably easier.

The standard range includes nine BSP connections from 1/4″ to 1″ and four OD tubes from 6mm to 20mm. Other connections and imperial tube sizes are also available.
