Festo
9984
Pneumatic valve VL/O-3-1/4
The Festo 9984 is a direct-controlled 3/2 open/closed monostable pneumatic industrial component featuring a plate seat structural design with a soft sealing principle and a negative overlap lap. It delivers a normal nominal flow rate of 800 l/min through G1/4 pneumatic working ports, operating within a pressure range of -0.095 MPa to 1 MPa (-0.95 bar to 10 bar) and an external pilot pressure of 0.1 MPa to 1 MPa (1 bar to 10 bar). Constructed with an IP65 degree of protection, a 30.5 mm width, a 32 mm width dimension, and a 7 mm nominal width, this unit utilizes an adjustable exhaust air function, mechanical spring reset, and reversible flow direction in any mounting position.

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.
