Nilon Diaphragm Valves a suitable for positive pressure and high vacuum application.
The diaphragm isolates the operating mechanism in the bonnet from the fluid in the pipeline. This
achieves two objectives one it ensures purity of the line fluid and two, the operating mechanism is not
corroded by the fluid and is therefore permanently protected against chemical attack. Maintenance of
these valves is very simple. By dismantling the bonnet from the body, the entire trim assembly can be
taken out for maintenance and the body remains in the pipeline. Thus the design permits online
maintenance and saves time and energy.

“Nilon” series Pinch valve is a modified version of laboratory pinchcock. A rubber sleeve is protected under
a cast iron casting. The fluid passing through does not come in contact with either body covering or any
other metal parts of the valve except the sleeve. Hence the body and other metal parts are almost permanently
not subjected to the corrosive action of the fluid. The flow through the valve is straight and full as that of a
pipeline, when the valve is fully open. Further, the collar of the sleeve eliminates gasket. The valve is simple
hand wheel operated of rising wheel type. Therefore the operation of the valve is just simple as other wheel
operated valve. The in-between stoppage will allow the desired throttling. Thus the valve offers positive
control over flowing media.

“Nilon” series Needle valves have a slender, tapered point at the end of the valve stem that is lowered
through the seat to restrict or block flow. Fluid flowing through the valve turns 90 degrees and passes
through an orifice that is the seat for a rod with a cone shaped tip. These small valves are widely used to
accurately regulate the flow of liquids and gases at low flow rates. The fine threading of the stem and the
large seat area allow for precise resistance to flow. Needle valves are used to control flow into delicate
gauges, which might be damaged by sudden surges of fluid under pressure. Needle valves are also used in
situations where the flow must be gradually brought to a halt and at other points where precise adjustments
of flow are necessary or where a small flow rate is desired. They can be used as both on/off valves and for
throttling service.

“Nilon” Series Plug valves, also called cock or stop-cock valves, date back to ancient times, where they were
developed for use in citywide Roman plumbing systems. Today, they remain one of the most widely used
valves for both on/off and throttling services. Their design is fairly simple; the body is comprised of three
main parts: body, cover and plug. The plug is a cylindrical, tapered, or generally cone-shaped device that
can be raised or lowered within the seat to maintain, restrict or completely shut off flow. The valve is opened
by rotation, with the plug itself being the only element that is capable of movement. Early models of plug
valves used metal-to-metal seals that were no lubricated. This design is still used, but problems with galling
and sticking limit their usefulness. The use of lubricant between the plug face and the seat eliminates most of
these problems. The lubricant helps to control leakage around the plug, reduces wear between the valve
contact surfaces, and slightly lifts the plug to reduce the operating torque required to operate the valve.

“Nilon” series Dual Plate Check Valve is an all purpose non return valve that is much stronger, lighter in
weight and smaller in size compared to a conventional swing check valve or lift check valve.
The Dual Plate Check Valve design is the outcome of attempts to solve the problems associated with
conventional swing check valve and lift check valve. The Dual Plate Check Valve employs two-spring-loaded
plates hinged on a central hinge pin. When the flow decreases, the plates close by the action of torsion spring
before flow reversal takes place. This design offers the twin advantages of No Water Hammer and Non Slam
simultaneously. All features put together make the Dual Plate Check Valve as the most efficient & versatile
design.
