Manifolds are specially designed Needle Valves for operation with most of the Fluids up to 6000 psig (414 barg) and on special request up to 15,000 psig (1035 barg) ratings. These valves are complete with PTFE gland packing or with Graphoil gland packing (For high temperature applications). Placing the gland packing below the stem thread ensures that the process does not get in contact with the Stem threads. Tightening of the upper gland body ensures perfect sealing of the gland packing and arrests leakage.
