Duplex Stainless Steel Globe Valves

Duplex Stainless Steel Globe ValvesWe are India's one of the most reputed manufacturers and suppliers of Duplex stainless steel Globe Valves. Duplex steel Globe valves is a linear motion valve and are designed primarily to stop, start and regulate the through flow. The mechanism of the disk of a DSS Globe valve can be totally removed from the flow path or it can completely close the flow path

Conventional duplex steel globe valves can be used for isolation and throttling services. Although these type of valves exhibit slightly higher pressure drops than straight through valves (e.g., DSS gate valve, plug valve, ball valves etc.), they may be used where the pressure drop through the valve is not a controlling factor to be concern.

The practical size limit for these duplex steel globe valves is NPS 12 (DN 300), because the entire system pressure exerted on the disc is transferred to the valve stem portion, Duplex Steel Globe valves larger than NPS 12 (DN 300) are an exception rather than the rule. Larger valves would require that enormous forces be exerted on the stem to open or close the valve under pressure. Although we have manufactured and supplied up to NPS 48 (DN 1200) size Duplex Stainless Steel Globe valves have been used and it worked properly at the project sight.

DSS Globe valves are extensively employed to control flow. We have method of considering the range of flow control, pressure drop, and duty while the designing of these metal Globe valve in our manufacturing manual to avoid premature failure and to assure satisfactory service to end user. Since all pressure ultimately goes to the trim and stem portion, we give more emphasizes more specially on valve trim designed of the valves, subjected to high-differential pressure-throttling service.

Generally the maximum differential pressure across the valve disc should not be exceeding 20 percent of the maximum upstream pressure or 200 psi (1380 kPa) whichever is less to avert premature failure and to make sure value for money to end user of these valves. Duplex stainless steel Globe Valves with special trim can be designed and manufactured by us for applications exceeding these differential pressure limits.

We can part these DSS globe valves in to three different types with co relating to its primary body designs.

 

Duplex Stainless Steel Globe Valves

Duplex Stainless Steel Globe Valves

Type : Tee Pattern or Z-body

Tee Pattern or Z-body Duplex Stainless Steel Globe ValvesTee Pattern or Z body Duplex Steel Globe valves manufactured and supplied by us are the common body type in Globe valves, with a typical Z-shaped diaphragm. In this type of valves, the horizontal setting of the seat allows the stem and disk components to travel perpendicular to the horizontal line. This designed valve has the lowest coefficient of flow and higher pressure drop. These type of valves are used in severe throttling services, such as in bypass pipe lines around a control valve. Duplex steel Tee-pattern Globe valves can be used in applications where pressure drop is not a matter of concern and throttling is required.

Duplex Stainless Steel Globe Valves

Type : Angle Pattern

Angle Pattern Duplex Stainless Steel Globe ValvesDuplex steel angle pattern Globe valves design manufactured and supplied by us are an modification of the basic Tee Pattern Duplex steel Globe valves. We have designed the ends of this DSS Globe valve at an angle of 90 degrees, and fluid flow occurs with a single 90 degrees turn. These valves have a slightly lower coefficient of flow than wye-pattern Duplex steel Globe valves. Our these valves can be used in applications that have periods of pulsating flow because of their capability to handle the slugging effect of this type of flow.

Duplex Stainless Steel Globe Valves

Type : Wye Pattern or Y-body

Wye Pattern or Y-body Duplex Stainless Steel Globe ValvesDuplex steel Wye pattern Globe valves design and manufactured by Neev Valves are an best possible solution for the high pressure drop, inherent in Globe valve series. This type of Globe valves gives a straighter flow path at full opening and offer the least resistance to flow because the seat and stem are designed to angle at approximately 45 degrees,. These valves can be cracked open for long periods without severe erosion. These globe valves are extensively used for throttling during seasonal or startup operations. The advantage of these type of valves is that it can be rod through to remove debris when used in drain lines that are normally closed.
