Valve manifolds are designed for connecting system impulse line & transmitters. These manifold consist of two valve configuration which allows for easy isolation, calibration, block and bleed for gauges, pressure switches and static pressure transmitting instruments. These manifolds are rugged in construction to withstand high pressures and temperatures. The manifolds are rated for pressures as high as 6000 PSI at 200 o F or 4000 PSI at 500 o F. with PTFE Packing. For a Higher Temperatures Grafoil Packing is used. These valve manifolds combine the functions of a tee,
