About Class 150 Swing Check Valve

Class 150 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.

Reliable Backflow Prevention

This swing check valve is engineered exclusively for non-return operation, helping prevent undesirable backflow in pipelines handling water, oil, or steam. Its renewable seat and robust construction deliver lasting performance and easy maintenance, ensuring operational safety for demanding industrial environments.

Versatile Installation

With face-to-face dimension compliance (ANSI B16.10) and a wide port range (2"-12"), the valve fits seamlessly into various pipelines. The flanged end connection allows for straightforward installation, reducing downtime during commissioning and maintenance phases.

High-Quality Materials and Coating

Manufactured from ASTM A216 WCB cast steel and featuring a rust-resistant coating, this swing check valve withstands harsh process conditions. The stainless-steel disc and spiral wound gasket enhance durability and maintain leak-tight integrity, even under fluctuating pressures and temperatures.

FAQ's of Class 150 Swing Check Valve:

Q: How does the Class 150 Swing Check Valve prevent backflow within a system?

A: The valve uses a swing-type disc mechanism that allows media to flow in only one direction; if flow reverses, the disc closes automatically, preventing backflow and protecting pumps, equipment, and pipelines.

Q: What media are suitable for use with this swing check valve?

A: This valve is compatible with water, oil, and steam, making it ideal for application in industrial, oil & gas, and water treatment processes.

Q: When should the renewable seat feature be utilized?

A: The renewable seat becomes relevant during maintenance or replacement intervals, allowing for easy refurbishment to extend valve service life and restore optimal sealing performance.

Q: Where can this valve be installed within a piping network?

A: It can be installed in horizontal or vertical pipelines with flanged connections where unidirectional, non-return flow control is required, typically downstream of pumps or in process lines.

Q: What is the process for installing this valve in a system?

A: Installation involves aligning the flanged ends with compatible pipeline flanges, securing with suitable bolts, and ensuring correct orientation for flow direction, as indicated on the valve body. A spiral wound gasket is used to secure a leak-tight joint.

Q: How does the rust-resistant coating benefit the valve in industrial environments?

A: The rust-resistant coating protects against corrosion caused by moisture and harsh chemicals, significantly extending the valve's lifespan and maintaining its operational reliability even under challenging conditions.
