Duplex Stainless Steel Flanged End Valves

 

We are manufacturers and suppliers of quality duplex steel flanged valves. These Duplex stainless steel valves are mechanical devices that controls the flow and pressure within a system or a standard process. These valves are essential engineered components of a pipeline system that conveys liquids, gases, vapors, slurries etc.

We are manufacturing different types of flanged valves in type or design of gate, globe, plug, ball, butterfly, check, diaphragm, pinch, pressure relief, control valves etc. Each of these typed valves has a different features and functional capabilities like Stopping and starting flow, Reduce or increase a flow, Controlling the direction of flow, Regulating a flow or process pressure, Relieve a pipe system of a certain pressure to serve the industrial purpose. We are manufacturing and supplying both type of valves self operated as well as manually operated or even these DSS valves can be operated with an actuator or pneumatic or hydraulic is operated.

 

Duplex steel Flanged End Ball Valves


We manufacture basically three type of duplex steel flanged ball valves . The full-port flanged ball valves internal diameter is equal to the inner diameter of the pipe to be installed. Venturi and reduced-port flanged ball valves are generally one pipe size smaller than the running pipe line size. Duplex stainless steel Flanged Ball valves are manufactured in different body configurations like Top entry Duplex Steel Flanged Ball valves allow access to valve internals for maintenance by removal of the valve Bonnet-cover. This type of valves facilitates maintenance engineers to not to remove valve from the pruning pipe system.

Split body Flanged Ball valves consists of a two parts, where one part is smaller as the other. The ball is inserted in the larger body part, and the smaller body part is assembled by a bolted connection. Further we can have these flanged ball valves body in Three pc, and one pc designs as well.

Duplex Steel Flanged End Gate Valves

 

Duplex steel Flanged Gate valves primary function is to start or stop liquid flow, and when a straight-line flow of fluid and minimum flow restriction are needed. In service. These valves allows only two positions i.e. either fully open or fully shut.

The disk of this duplex steel Gate valve is completely removed when it is fully open; the disk is fully drawn up into the valve Bonnet. This mechanism allows flow through the valve at the same inside diameter as the pipe line in which the valve is installed. These flanged gate valve are generally used for a wide range of liquids and provides a tight seal when this valves are closed.
