About Valve with Extended Stem
Ductile iron or stainless steel made Valve with Extended Stem is suitable for normal temperature prone working condition. Featured with gate type structure, this valve is suitable for water transferring pipelines. It comprises of standard accessories like ductile iron or cast iron gland and bonnet, stainless steel stem and ductile iron disc that has EPDM or NBR seal. This Valve with Extended Stem can be operated pneumatically/electrically. Quality of this valve has been verified on the basis of seat pressure, shell pressure and working pressure tests. Designed by skilled personnel, this product is reckoned for its long working life and accurate dimension.
Engineered for Demanding EnvironmentsThese valves are specifically constructed to endure harsh settings such as insulated or subterranean pipelines. Due to their high corrosion resistance and durable stainless steel material, these valves perform reliably even in chemically aggressive or high-moisture applications, providing safety and stability across water, oil, gas, and steam media.
Customization and VersatilityWith stem extensions of up to 500 mm and options for flanged or threaded end connections, the design fits seamlessly into existing pipeline systems. The two-piece or three-piece construction allows for easy maintenance or modification, making it adaptable to varied requirements in chemical, water, oil, and gas industries across India.
FAQs of Valve with Extended Stem:
Q: How does the extended stem benefit the valves operation in buried pipelines?
A: The extended stem makes it easier to access and operate the valve even when it is installed in insulated or buried pipelines, ensuring smooth manual control without needing to dig or remove insulation.
Q: What industries commonly use these extended stem valves?
A: These valves are widely utilized in chemical, water, oil, and gas industries where insulated or deeply installed pipelines are common, thanks to their high durability, corrosion resistance, and adaptability.
Q: When should I choose a PTFE or metal sealing option for my valve application?
A: PTFE sealing is ideal for handling corrosive or aggressive media, offering chemical resistance and minimal leakage, while metal sealing is suitable for higher temperature or pressure environments requiring robust sealing.
Q: Where can I install valves with extended stems for optimal performance?
A: Install these valves in pipeline sections that are insulated, buried underground, or otherwise difficult to access directly; the extended stem design ensures reliable operation in such challenging locations.
Q: What is the process for customizing stem extension length for my valve?
A: You can specify your desired stem extension length (up to 500 mm or as needed) during the ordering process. The manufacturer customizes the valve to your specifications to ensure a perfect fit and functional operation.
Q: How do the two-piece and three-piece body designs differ in usage?
A: Two-piece valves are generally easier to install in tight spaces, while three-piece designs allow for in-line maintenance or cleaning without removing the valve from the pipeline, adding flexibility to your operations.
Q: What are the main benefits of using a valve with a polished stainless steel surface?
A: A polished stainless steel surface not only enhances corrosion resistance but also makes the valve easier to clean and maintain, which is essential for high-hygiene or chemically exposed application environments.
