Throttle valve GRO-QS-6

The Festo 193973 is a flow control industrial component featuring QS-6 pneumatic connections on both ports and a manual knurled screw adjusting element. Built with a PA-reinforced housing, NBR seals, and a POM releasing ring, this 22 g valve operates from 0 bar to 10 bar within an ambient and medium temperature range of -10 °C to 60 °C. It delivers a standard nominal flow rate of 245 l/min in the flow control direction and 430 l/min in the non-return direction using compressed air as per ISO 8573-1:2010 [7:4:4]. Designed for mounting via front panel, through-hole, or accessories in any position, it supports ATEX explosion protection for zones 1, 2, 21, and 22.

Why 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.
