Name: Festo 530044 Piloted non return valve HGL-3/8-QS-10
Brand: Festo

Piloted non return valve HGL-3/8-QS-10

The Festo part number 530044 is a pneumatically actuated industrial component featuring an unlockable check valve function, a QS-10 pneumatic connection 1, a G3/8 pneumatic connection 2, and a G1/4 pilot air port 21. Designed for screw-in mounting with an external thread in any mounting position, this unit operates within a pressure range of 0.05 MPa to 1 MPa (0.5 bar to 10 bar) and a pilot pressure of 1 bar to 10 bar (14.5 psi to 145 psi). It delivers a standard flow rate 1->2 of 1300 l/min at 6-0 and 890 l/min at 6-5 while utilizing compressed air according to ISO 8573-1:2010 [7:4:4] with possible oil lubrication.

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.
