Technical Specifications:

2WAY, 3WAY and 5-Valve Instrument Manifolds.

Options for Mounting:

Remote mounting “R” Type Manifold (Pipe to Pipe)

Direct Mounting “T” Type Manifold (Pipe to flange, Flange to Pipe)

Direct Mounting “H” Type Manifold (Pipe to flange, Flange to Pipe)

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.
