Weir Diaphragm Valves

Weir Diaphragm Valves

PTFE Lined Diaphragm Valves

4Matic Weir type Diaphragm valves are specifically designed for resilient and severe service applications such as in the mining, chemicals and water treatment industries etc. 4Matic Weir Diaphragm Valves are used to control the flow of media that is corrosive or erosive in nature. The weir-type diaphragm valves can be successfully utilized as a control valve or in the case of manual proportionate control of a fluid is required. Size Range: ½” (15mm) to 12” (300 mm).

Size Range: 15mm to 300 mm
MOC: SG Iron, Carbon steel and stainless steel
Lining Options: PP (Polypropylene), PTFE, FEP, PFA, PVDF etc.
Operation: Manual /Pneumatic Actuator operated (fail to open, fail to close or double acting) / Electric actuator operated.

As an ISO certified company, 4Matic range of Lined Diaphragm valves blueprint is in accordance with PED 1128.  The total production of valves is subjected to Hydro as well as Pneumatic Test so as to assure totally dependable working of valves. Flange dimensions in DIN, ANSI and JIS standards are available. The lining of all valves is done through the most recent injection molding procedure which is best in class. For low permeation and assertive and corrosive chemicals TFM diaphragm pin type is made use of instead of a 3 layer diaphragm for better performance.
