Rising stem gate valve manufacturers
Valvesonly Europe leading Rising stem gate valve manufacturers in Germany, offers top-notch DIN Rising stem gate valves for commercial applications. The valves are appropriate for a variety of industries, including power plants, water treatment, chemical processing, and oil and gas, because they are made to provide exact visual indication of valve position together with efficient fluid control.
By meeting the criteria of the Deutsches Institut für Normung (DIN), a DIN rising stem gate valve offers superior quality, durability, and compatibility with European pipe systems. Better control and dependability are provided by the rising stem mechanism, which makes it easier to determine whether the valve is open or closed.
What is the Operation of a DIN Rising Stem Gate Valve?
When a rising stem gate valve is opened or closed, the stem seems to move up and down using a linear motion mechanism. The following make up the operation principle:
Opening the Valve: The stem rises as the actuator or handwheel is turned, lifting the gate (a parallel disc or wedge) to allow fluid to flow freely.
Closing the Valve: To totally stop the flow, the stem drops the gate as it falls.
Visual Indication: Accurate operation is made possible by the rising stem's clear valve position indication.
Sealing Mechanism: To ensure leak-proof performance and extended service life, the valve uses either soft or metal-to-metal sealing.
DIN rising stem gate valves are perfect for systems requiring precise fluid management as well as applications requiring resistance to high temperatures and pressures.
Advantages:
Easy Position Indication: It is easy to check the state of the valve due to the visible stem movement.
Low Fluid Resistance: Smooth and high-flow rate fluid passage is ensured by the full-bore design.
Sure Shut-Off: Minimizes leakage and pressure drop with a tighter seal.
Long Life: Made of high-grade materials that are resistant to corrosion, such as ductile iron, stainless steel, and cast iron.
Suitable for High-Temperature Processes: can handle operations with high pressure and temperature.
Low maintenance: few moving parts and a streamlined design result in low maintenance.
Parts:
Valve Body: Constructed of cast iron, ductile iron, carbon steel, or stainless steel.
Gate (Wedge or Parallel Disc): Regulates the flow of fluids.
Rising Stem: Gives visual signal of valve position.
Bonnet: Encloses the stem and sealing elements.
Seals & Gaskets: Protect against leakage.
Actuator/Handwheel: Employed to manually or automatically control the valve.
Types of DIN Rising Stem Gate Valves:
Solid Wedge Gate Valve: Most suitable for high-temperature and pressure applications.
Flexible Wedge Gate Valve: Provides improved sealing and accounts for thermal expansion.
Double Disc Gate Valve: Offers close shut-off with little wear on sealing surfaces.
Bellow Sealed Gate Valve: Used in applications involving harmful fluids, preventing leakage.
Pressure Seal Gate Valve: Applied in oil and high-pressure steam pipelines.
Difference between Rising Stem and Non- Rising Stem gate valve:
Both valves serve the same function, but differ in design and operation.
Stem Movement: In rising stem gate valves, the stem rises vertically when the valve is operated, whereas in non-rising stem gate valves, the stem turns to open the valve.
Visibility: Rising stem gate valves have a clear visible indication of the valve position in relation to stem movement, while there is no external visible indication of the valve position in relation to stem movement in non-rising stem gate valves.
Construction: In both of them, the stem is directly attached to the gate; however, in rising stem gate valves, its movement causes the movement of the gate, whereas in non-rising stem gate valves, the stem rotates in the bonnet and is attached to the gate internally.
Design: Rising stem gate valves are generally applied for operations where valve position indication is visually significant, i.e., manual operations or where there is adequate space available for vertical stem motion. Non-rising stem gate valves are appropriate for those applications where vertical space is negligible or external visibility of stem travel is unnecessary.
