Rising Stem Stainless Steel Gate Valve Manufacturer in India

A rising stem stainless steel gate valve is a multi-turn isolation valve in which the stem moves upward and downward with the gate, providing a visible indication of valve position. Its OS&Y arrangement keeps the operating thread outside the process fluid, while stainless steel construction is suited to corrosive and demanding process services. Speciality Valve manufactures and offers rising stem stainless steel gate valve for industrial isolation applications. Speciality Valve provides configurations based on size, pressure class, material grade, trim and connection requirements. 

Rising Stem Stainless Steel Gate Valve Applications:

• Chloride-Containing Process Lines: Used where stainless construction is selected to resist chloride exposure in compatible process media.

• Chemical Transfer Piping: Applied to corrosive-fluid lines requiring full isolation rather than continuous throttling.

• Offshore Utility Piping: Suitable for compatible seawater, utility-water and process services where corrosion resistance is required.

• High-Purity Process Systems: Used for isolation in selected stainless-steel process piping where clean internal surfaces are important.

• Corrosive Gas Handling: Applied to compatible gas systems where stainless steel provides greater resistance than carbon-steel construction.

Rising Stem Stainless Steel Gate Valve Technical Specifications:

Rising Stem Gate Valve Construction:

• OS&Y Arrangement: Places the operating screw outside the pressure-containing cavity.

• Rising Stem: Moves vertically with the gate and provides external position indication.

• Wedge: Flexible or solid construction can be selected according to service requirements.

• Body: Stainless steel pressure-containing construction for compatible corrosive duties.

• Seat: Integral or renewable seating arrangements are available according to design.

• Bonnet: Bolted or pressure-seal construction can be selected according to pressure and service.

• Backseat: Provided in applicable designs for additional stem sealing when fully open.

• Packing: Material selected according to temperature, medium and emissions requirements.

Valve Operating Characteristics:

• Visible Position: External stem movement allows the operator to identify the approximate gate position.

• Full Opening: The gate moves clear of the flow passage when fully open.

• Isolation Duty: Intended primarily for fully open or fully closed operation.

• Bidirectional Shut-Off: Suitable wedge configurations can provide isolation from either direction.

• Manual Operation: Handwheel provides multi-turn mechanical operation.

• Gear Assistance: Gearboxes can be used where greater operating torque is required.

• Actuated Operation: Electric or pneumatic actuation can be specified for automated isolation.
