Features
  • It is a combination of needle & manifold valves thus redusing the number of joints.
  • Spindle : ground and thread rolled.stem tip 17-4ph for long life.
  • Dust cap protects stem threads from external contamination leak tight seal with low operating torque heat code traceability ball hard chrome plated for smooth opertions.
Testing
  • Hydrostatic shell test is performed at 1.5 times the working pressure.
  • 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.
  • Optional test are available upon request
