Diaphragm Valve:

Diaphragm Valve: Weir Type

Versatile ‘FSE’ Diaphragm Valves Weir Type, with pneumatic and actuator options, provide zero
leakage fluid passage, and are used in Minerals, Chemical, Water treatment and
Pharmaceutical applications.

Overview

The Flowshree Engineers Diaphragm Valve is designed for water & effluent treatment, desalination
plants, power plants, chemicals & process plants, fertilizers and mining. The valves are simple in
construction, effective for liquids and gases encountered with corrosion, abrasion, clogging &
contamination.

Key features/benefits

• Bonnet assembly Isolated from fluid being handled
• Positive leak tight closure
• Streamlined Fluid passage
• Glandless design – Zero leakage to atmosphere
• Suitable for on-off and throttle application
• Pressure and vacuum handling
• Position Indicator
• Wide choice of Body lining materials & Diaphragms

Diaphragm Valve: Straight Through

Versatile ‘FSE’ Diaphragm Valves, with pneumatic and actuator options, provide zero leakage fluid
passage, and are used in Minerals, Chemical, Water treatment and Pharmaceutical applications.

‘FSE’ Diaphragm Valves are designed for water & effluent treatment, desalination plants, power plants,
chemicals & process plants, fertilizers and mining. The valves are simple in construction, effective for
liquids and gases encountered with corrosion, abrasion, clogging & contamination.

The wide variety of body materials and linings available mean our Diaphragm Valves are designed for
use where the process may demand other valves be constructed of exotic and often expensive alloys due
to corrosion and erosion. Equally suited to on and off, or flow control applications, a diaphragm valve is
designed to handle positive pressures or high vacuum. Due to the wide range of material options it will
handle almost all applications within its temperature and pressure ranges (175°C max. and 16 bar max.)
and as such is used in almost every industry on both corrosive and abrasive applications. All working
parts are isolated from the line media which enhances its reliability. Maintenance is a simple task with the
body remaining in the pipe, the valve thus being field serviceable. It has linear flow characteristics which
makes it well suited to throttling or modulating duties. On/off and control automation is possible with the
use of modern compact actuators and accessories.

Key features/benefits

• Bonnet assembly isolated from fluid being handled
• Positive leak tight closure
• Streamlined fluid passage
• Glandless design – zero leakage to atmosphere
• Suitable for on-off and throttle application
• Pressure and vacuum handling
• Position Indicator
• Wide choice of body lining materials & diaphragms
• Easy line maintenance
• Cost effective
