With rich expertise, we are offering a wide range of Needle Valves that is generally used in flow metering applications, especially when a constant, calibrated, low flow rate must be maintained for some time. Our SS needle valves are appreciated in the market for low operating torque and high tensile strength. Further, these are provided in proper packaging to the clients to prevent wear and tear during transportation. Needle Valves or Shut-Off Valves are designed to Isolate, Calibrate and Drain Process Lines by Line Mounting.
Testing
- Standard test: each valves is tested with nitrogen at 1,000 psi for seat & packing leakage, with a max. Allowable leak rate of 0.1 std.cm3/min.
- Hydro test: performed with pure water at 1-1/2 times of the working pressure.
