Festo
536031
Pneumatic valve VL/O-3-3/4-EX
The Festo 536031 is a 3/2 open/closed monostable industrial component featuring a plate seat structural design, soft sealing principle, and mechanical spring reset method. This pneumatically actuated valve operates within a pressure range of -0.095 MPa to 1 MPa (-0.95 bar to 10 bar) and delivers a normal nominal flow rate of 7500 l/min through G3/4 pneumatic working ports. Certified with CE and UKCA markings for ATEX category II 2G gas and II 2D dust environments, it supports an explosive ambient temperature range of -10ÞgC to +60ÞgC with Ex h IIC T4 Gb and Ex h IIIC T130ÞgC Db ignition protection.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
