Diaphragm Valves

Diaphragm Valves consists of a valve body with two or more ports. The diaphragm valve was developed for use in industrial applications. Later on the design was adapted for use in the bio-pharmaceutical industry by using compliant materials that can withstand sanitizing and sterilizing methods. Diaphragm valves can be manual or automated. Their application is generally as shut-off valves in process systems within the industrial, food and beverage, pharmaceutical and biotech industries.

  1. Weir-Type Diaphragm Valves

  2. Straight-Through Diaphragm Valves

  3. Thread Diaphragm Valves

1.Weir-Type Diaphragm Valves

Weir Type Diaphragm valve is generally produced in large sizes. The raised weir reduces the amount of diaphragm travel from the fully open to the fully closed position, thus reducing the amount of stress and strain in the diaphragm.

Weir Type Diaphragm valve Range

Size :1/ 2”~16”(DN15~DN300)

Rating : PN6, PN10, PN16, ANSI 125, ANSI 150

Body Materials : Cast Steel, Cast Iron, Ductile Iron, Stainless Steel, Duplex Steel

2.Straight-Through Diaphragm Valves

When the straightway valve is open, its diaphragm lifts high for full streamline flow in either direction. When the valve is closed, the diaphragm seals tight for positive closure even with gritty or fibrous materials in the line.
