Key Features

  • Some of the key features of our superior quality high precision manifold valve design are Units duly designed to withstand system static pressure.
  • The manifold valves are manufactured to endure all differential pressure and liquid level application needs.
  • Units have been manufactured according to a compact assembly design. This translates into complete products which have a reduced weight and size.
  • The design and manufacturing details of the valve manifold units ensure fewer chances of potential leak points.
  • All units undergo extensive testing procedures to assess quality and precision before being supplied to customers.
  • Units are available in a stainless steel 316 material series design.
  • The units have been manufactured to ensure easy installation and hassle free maintenance in aggressive industrial systems.

Bonnet Assembly

  • Bonnet : back seated blow out proof.
  • Spindle : ground and thread rolled. Packing below thread.
  • Spindle Tip : non-rotating tip shut-off type & soft seated.
  • Dust cap : dust cap protects stem threads from external contamination heat code traceability.
