Block & Bleed
One-piece block and bleed on an ASA raised-face flange, bolted straight to the vessel or process pipe for primary isolation.
Manifolds
Block & Bleed
Designed for one-piece block and bleed assemblies for primary isolation of pressure take-offs, where the valve is directly mounted to the vessel or process pipe. Instruments may be directly mounted to the valve outlet or alternatively remotely mounted with gauge lines / impulse pipe work.
The process end is an ASA raised-face flange in 1/2", 3/4" and 1", each in 150, 300, 600, 900/1500 and 2500 lb ratings. Face-to-face A-RF runs 57 mm at 150 lb to 67 mm at 2500 lb, and overall height B runs 89 mm to 159 mm, across the fifteen size-and-rating combinations. Ask for the dimension sheet for a specific combination.
Four mounting bolts to IS 1364-1960 are supplied with the manifold.
