New choice for Weir Diaphragm Valve(lined diaphragm valve,diaphragm valve)

Weir Diaphragm Valve(lined diaphragm valve,diaphragm valve)

OVERVIEW:

Diaphragm valves have always been popular in the chemical

industry due to their simple construction and ease of containing

the fluid without any outside leakpaths.

Available in Weir  type design only.

Characteristics of design:

 The diaphragm is made of various Fluoroplastic material with

synthetic rubber backing.

 The diaphragm is generally the only wearing part and is easy

and inexpensive to replace.

Availab le with: Handwheel operated, pneumatic and electric

actuator.

APPLICATION AREAS IN INDUSTRIES: 
Where highly corrosive materials are used in any area of Chemical Process Industry.
Provides improved operational safety for personnel, processes and plants when handling extremely hazardous materials.
Where product purity is critical viz. Foods, Pharmaceuticals and Fine Chemicals.
Where downtime, due to pipe replacement, needs to be avoided.
Where environmental pollution is to be controlled.

ADVANTAGES:
Non-stick property
Self sealing faces
High resistance to Thermal/Mechanical shock
Suitable for pressure and vacuum application
Easy to install
Has long life and Zero maintenance
More economical than glass lined and special alloys
Can be tailor made to suit customer requirements
