JLS Valve Brochure (PDF)

Higher pressure isolation valves with ease of operation

High integrity shut-off valve for higher pressure hydraulic or pneumatic (only dry air and gas) systems (note that for use with pneumatic applications above 20bar valve must be degreased - please indicate on order).

Allows finger tip effort closure due to internal pressure balancing, rather than considerable effort on conventional valves, at these pressures.

Incorporates non-rotating stem for long life positive sealing and a non-rising handwheel.

Standard type 509 valves are supplied with stainless steel spindles, nitrile rubber gland seal and delrin seats.
