Duplex Stainless Steel Ball Valves

We are most prominent manufacturers and suppliers of Duplex Steel Ball Valves in India. DSS ball valve is designed with a spherical disc wich is in geneal known as ball (one of the component of the valve) which controls the flow through it. The duplex steel ball has a particular diameter hole or port, through the middle so that flow will start when the port is in straight line with both ends of the valve. The hole is made perpendicular to the ends of the valve to block the flow. This is common or universal practice that the handle or lever is set in line with the port position letting site engineers to see the valve's position. The ball valve, along with the butterfly valve and plug valve, are part of the family of quarter turn valves.

Duplex Stainless Steel Ball ValvesDuplex Steel Ball valves are not only durable and usually work to achieve perfect shutoff even after years of disuse but also have a great feature of anti corrosive. This is why these valves can be the excellent choice for shutoff applications. DSS Ball valves are generally preferred to DSS globe valves and DSS gate valves for this reason. These valves do not offer the fine control that may be necessary in throttling applications but are sometimes used for this purpose.

Duplex steel Ball valves are used extensively in industrial applications because they are very versatile, sustains at the pressures up to 1000 bar and temperatures up to 752°F (500°C) depending on the ball valve design selection. We are manufacturing and supplying duplex steel ball valves in sizes range typically from 1/2 inch to 48 inches. These valves are also being prefffered by engineers and various project design makers because of it' is easy tooperate and repair. We manufacture and supply balls in all our duplex stainless steel ball valves chrome plated to make it ensure for more durablity.

 

Types of Duplex Steel Ball Valves

There are hundreds of designs and combinations we are manufacturing and supplieng to various industries since a decade. But still we can have a brief information on some standard and regularly manufactured duplex steel valves in our factory.

 

 

Duplex Steel Ball Valves

Type: Full Port

We are manufacturing Duplex steel FP ball valves where in the ball of the valve is over sized and by which we can have the hole of that ball same as what of run pipe. The main purpose of this design is to have unrestricted flow with lower friction loss, but these duplex steel ball valves are comparitively bigger in body size and ultimately this impact on price.

 

Duplex Steel Ball Valves

Type: Reducing Port

We are manufacturing Duplex steel RP ball valves which is also called as reduced bore duplex steel ball valves where in the ball of the valve have one size smaller hole while comparing to run pipe where this DSS ball vvale have been installed.

 

Duplex Steel Ball Valves

Type: V Port

We are manufacturing Duplex steel V port ball valves where in the seat is V shaped designed. This type of valve design need more robust construction due to higher velocities of the fluids, which might damage a standard valve.

 

Duplex Steel Ball Valves

Type : Trunnion Mounted

Duplex steel trunnion ball valve has additional mechanical anchoring to the ball at the top and the bottom. This type is suitable for larger size and higher pressure valves ( may be above 4 inches and 40 bars).

 

Duplex Steel Ball Valves

Type : Floating

Duplex steel floating ball valve manufactured and supplied by us is one where the ball is not held in place by the trunnion. In this type of valves the seating mechanism to compress under the ball pressing against it.
