Non return valve H-QSM-5/32-U

The Festo part number 190841 is an aluminum industrial component featuring a non-return valve function with QS-5/32 pneumatic connections on both ports for in-line installation. It delivers a normal nominal flow rate of 139 l/min across an operating pressure range of -1 bar to 10 bar, requiring a minimum differential pressure of 0.1 bar to open and 0.2 bar to close. Weighing 5.3 g, this RoHS-compliant RoHS component operates with compressed air per ISO 8573-1:2010 [7:-:-] and accommodates oil lubrication which is required for further use within an ambient temperature range of 0 °C to 60 °C.

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. 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.
