About Pressure Sealed Check Valves

FlowBiz Exports Pvt Ltd Valves is a High Quality Tilting Disc Check Valves Manufacturer in Mumbai, Maharashtra, India. We are a leading manufacturer of Tilting Disc Check Valves in Mumbai and nearby areas.

Pressure Sealed Check Valves are intended for high pressure, high temperature applications in all types of fluid except where severe coking is a factor. The design and material selections provide excellent service in steam-generation stations, industrial chemical plants and thermal power plants.

Applications:

Check valves are used to prevent backflow and maintain pressure. They are commonly used as: a backup in case a pump fails, to help compressors and reciprocating pumps function, and when the system pressure exceeds the primary equipment capabilities. Check valves can be seen in industries such as refining, petrochemical, chemical, etc., oilfield production, water, steam, refining petro, and viscous fluids. Check valves are also commonly found in waste-water management systems and in manufacturing.

Precision Engineering for Demanding Applications

Our pressure sealed check valves are meticulously built to comply with stringent standards such as ASME B16.10, API 598, and BS 1868. The valves are manufactured from premium carbon steel, alloy steel, or stainless steel and finished with an anti-corrosive coating to withstand extreme industrial environments. They're expertly designed for high-pressure pipelines, refineries, and steam systems.

Advanced Sealing and Flow Assurance

Fitted with stainless steel gaskets reinforced with graphite or highly heat-resistant alloys, these swing check valves offer exceptional sealing integrity. The unit's metal-to-metal or soft-seated options assure tight shutoff and reliable non-return service in high-temperature conditions, making them a preferred choice for critical flow control in power generation and oil & gas sectors.

Versatile Design and Easy Integration

With face-to-face and end connection dimensions conforming to leading ASME and BS norms, integration into new or existing setups becomes straightforward. Shot blasted, painted exteriors, and flexible connection types-which include both flanged and butt weld ends-provide adaptability across a spectrum of pipeline configurations, all while safeguarding long-term valve performance.

FAQ's of Pressure Sealed Check Valves:

Q: How does a pressure sealed check valve ensure unidirectional flow in high-pressure systems?

A: The pressure sealed check valve is designed as a swing type, allowing fluid to pass in one direction only. When the flow reverses, the disc swings shut automatically, preventing backflow and ensuring the non-return function. This is particularly critical in high-pressure and high-temperature pipelines for safety and equipment protection.

Q: What standards do these check valves adhere to for testing and construction?

A: Our pressure sealed check valves comply with rigorous construction standards such as ASME B16.34 and BS 1868. For face-to-face dimensions, they follow ASME B16.10, while testing is done according to API 598 and BS 6755 to assure reliable performance and safety under various operational conditions.

Q: When should I choose a pressure sealed check valve over other valve types?

A: Pressure sealed check valves are ideally suited for services involving high pressure and high temperature, such as in power plants, refineries, and steam lines. Their design offers superior sealing and safety advantages in such demanding environments compared to conventional check valves.

Q: Where can these valves be installed, and what are the connection options?

A: These check valves are suitable for installation in steam, oil, gas, and water pipelines in industries like petrochemicals and power generation. They are available with flanged or butt weld end connections, conforming to ASME B16.5 and ASME B16.25 standards for versatile system integration.

Q: What is the process for maintaining a pressure sealed check valve?

A: Regular inspections for leakage, seat wear, or disc integrity should be performed. The robust design, including stellite overlay seat rings and corrosion-resistant coatings, minimizes maintenance needs. When necessary, servicing can be done without removing the valve from the line, especially for metal-seated models.

Q: How does the anti-corrosive coating benefit valve longevity?

A: The anti-corrosive coating protects the valve's body from harsh operating environments, such as corrosive media or extreme weather, significantly extending the valve's service life and maintaining optimal performance in industrial applications.
