Festo
1915543
Ball valve actuator unit VZBA-1/4"-GGG-63-32L-F0304-V4V4T-PS30-R-90-4-C
The Festo 1915543 is a 3-way pneumatic ball valve featuring an L bore, an Rp1⁄4 fitting connection, and a nominal width DN of 8 in an in-line installation design with any mounting position. Constructed from high-alloy stainless steel with RoHS compliance and VDMA24364 Zone III LABS conformity, this component handles operating pressures from 6 bar to 8.4 bar, a nominal pressure PN of 63, and medium temperatures ranging from -10 °C to 200 °C. It accommodates compressed air, inert gas, water without water vapor, and neutral liquids, supported by a flow rate Kv type L of 4.5 m³/h, explosion groups IIC and IIIC, and a slot direction matching the flow direction for switching position indication.

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.
