Festo
4577
Toggle lever valve H-5/3-1/4
The Festo 4577 is a manually actuated 5/3-way closed industrial component featuring a piloted type of control and a non-reversible flow direction with soft sealing. This unit operates within a pressure range of 0.2 MPa to 1 MPa (2 bar to 10 bar), achieves a normal nominal flow rate of 680 l/min at a nominal width of 7 mm, and utilizes G1/4 pneumatic working ports across connections 1, 2, and 3. Incorporating a mechanical spring reset method, the 1060 g assembly complies with VDMA24364-B1/B2-L LABS conformity and functions within an ambient temperature range of -10 °C to 60 °C.

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.
