210402-MFC

210402-MFC is a 210402 series block & bleed, soft seat needle valve. It combines isolating and venting in a single valve, eliminating the need for tubing and fittings. The block valve isolates the downstream process fluids and the bleed valve exhausts upstream fluids enabling static pressure transmitters, switches or gauges to be removed without disturbing the permanent piping installation. Block valve is located on the left side and the bleed valve is located on top in a 90° orientation, venting is to the right. It also feature a replaceable Delrin® seat, and straight through porting for bidirectional, high capacity flow and easy roddable cleaning.
