Stainless Steel Blow Down Valve
A stainless needle-type blow-down valve for draining and venting instrument lines and manifolds.
Size1/4" to 2"Pressure3000 PSI (WOG)BodyGlobe pattern
The stainless steel blow-down valve provides the controlled vent and drain function needed when isolating or recalibrating instrument lines, manifolds and gauge hook-ups. A tapered needle seats into a small integral seat for fine flow regulation, letting trapped pressure be bled off smoothly rather than dumped, then sealing tight once the line is clear. Its corrosion-resistant 316 body suits the same instrument and sampling service as the manifolds and needle valves it is fitted to.
