About Class 600 Swing Check Valve

Class 600 Swing Check Valve

The API BS 1868 series of Swing Check Valves is exceptionally sturdy, rugged and durable, with a reputation for quality, integrity, and long service.

They are designed for tight sealing and ease of operation. The valves are available flanged & butt-weld ends in pressure rating from ASME Class 150 to Class 2500, and in a variety of materials of construction.

Check Valves are of swing-type and bolted-cover construction. They conform to BS 1868 and also meet the general requirements of API 600, including shell wall thickness.

Main features :

Bolted body-cover design, seal welded & Valves with pressure seal cover
Bolted body-cover joints provided with spiral-wound stainless steel gasket and graphite filler for maximum protection against leaks
Die-formed graphite inner packing rings and braided graphite end rings with Inconel wire reinforcement and corrosion inhibitor
T-head stem-disc connection of gate valve fully meets strength requirements of API 602 and API 598
Rolled ACME thread on the stem for smooth operation
Tapered shoulder on the stem for back seating
Self-aligning type gland assembly with stud-and-nut tightening
Integral hard-faced body seat for globe and check valves
Spring-loaded disc on check valves suitable for no horizontal applications too
Gate and globe valves can be offered with electrical actuators
Austenitic SS forging for body and bonnet of Cryogenic valves, resulting in excellent impact strength, minimal heat loss, and resistance to corrosion
Valves can be offered to NACE MR-0175 and other special NACE requirements

Cast steel ASME B16.34 Swing Check Valves Pressure Seal Bonnet design

The ASME B16.34 Swing Check, and Y Type Swing Check Valves feature a pressure seal bonnet design for high-pressure services. These valves are extensively used in high pressure and high-temperature steam, oil, gas, chemical, and water applications in thermal power plants, fertilizer plants, petrochemical plants, and refineries. These valves are available in butt weld ends in pressure ratings of Classes 900, 1500 and 2500, and come in carbon steel and alloy steel construction.

Versatile End Connections and Material Options

This swing check valve supports flanged, butt weld, and socket weld end connections, making it adaptable for various pipeline requirements. Customers can select bodies made from ASTM A216 WCB, A351 CF8, or CF8M, offering compatibility and durability for a range of applications. Stainless steel and alloy steel disc options enhance corrosion resistance and ensure long-term reliability.

Precision Engineering and High Standards

Designed in accordance with API 6D and BS EN ISO 14341, this valve is crafted to meet industry-leading specifications. The bolted bonnet structure-tested under API 598-provides excellent leakage prevention, while metal or soft seated options further improve operational reliability. With an anti-corrosive coating, the valve withstands harsh conditions for extended service life.

Broad Application and Operational Efficiency

Ideal for water, oil, and gas flow control, the Class 600 Swing Check Valve excels in pipelines, petrochemical facilities, and power plants. Its non-return, automatic operation prevents reverse flow, promoting safe, efficient media transport. The manual power option ensures straightforward operation, with leak-tight performance (Class VI) across temperatures from -20C up to 425C.

FAQ's of Class 600 Swing Check Valve:

Q: How does the Class 600 Swing Check Valve function in a pipeline system?

A: This swing check valve operates automatically as a non-return valve, allowing flow in one direction while preventing backflow. The swing-type disc opens with forward flow and closes upon flow reversal, ensuring media only moves as intended without manual intervention.

Q: What are the material options available for the valve body and disc?

A: Body materials include ASTM A216 WCB, A351 CF8, and CF8M, while disc options are stainless steel and alloy steel. These materials provide exceptional durability, corrosion resistance, and suitability for diverse media such as water, oil, and gases.

Q: When should I choose metal seated versus soft seated options?

A: Metal seated valves are recommended for high-temperature or abrasive service, offering enhanced longevity and resistance. Soft seated valves are preferable when tight shut-off and minimal leakage are required, especially in low-pressure or clean media environments.

Q: Where is this swing check valve commonly applied?

A: It is widely used in pipelines, oil and gas facilities, petrochemical plants, and power generation systems. The valve's robust construction allows for reliable performance in demanding industrial settings across India and international markets.

Q: What is the process for installing the valve with different end connections?

A: Depending on the chosen end connection-flanged, butt weld, or socket weld-installation involves either bolting the valve to mating flanges, welding directly to the pipeline, or fitting within socket weld ends. Proper alignment and sealing are critical for optimal performance during installation.

Q: What benefits does this valve offer over other non-return valves?

A: With its bolted cover, anti-corrosive coatings, and adherence to API and ISO standards, the valve delivers superior leakage control (Class VI), broad temperature tolerance, and rugged reliability. Flexibility in material and connection type ensures adaptability for varying project needs.
