About RTJ End Swing Check Valve

RTJ End Swing Check Valve is used as essential part of water transferring pipelines. This type of valve is suitable for high/medium/normal temperature prone working condition. Port size of this valve ranges between 1/4 inch to 4 inch. Developed from stainless steel, this RTJ End Swing Check Valve features BSPT/NPT/BSPP threading. It comprises of standard accessories like bonnet gasket, swing type disc, bolted bonnet, eye bolt etc. Standard of this product has been tested on the basis of its longevity, surface finish and strength.

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.

Robust Design for Demanding Applications

This RTJ End Swing Check Valve features a swing-type non-return mechanism to ensure fluid flows only in the intended direction. Its construction from forged or cast steel, with alloy or stainless steel disc and hard-faced seating options, ensures resilience and longevity even in severe service environments like oil, gas, and power plants.

Certified Performance and Reliable Operation

Conforming to API 6D, ASME B16.34, and API 598 standards, each valve undergoes rigorous hydrostatic and pneumatic testing before delivery. The design guarantees automatic operation using the system's flow pressure, requiring no manual intervention or external power sources. This results in reliable backflow prevention with minimal maintenance.

Flexible Installation and Versatile Application

With flanged RTJ ends as per ASME B16.5 and customizable surface coatings, the valve integrates seamlessly into various pipeline configurations. Available in sizes from DN50 to DN900 and pressure ratings from Class 150 to 2500, it accommodates a broad spectrum of operating conditions and media including water, oil, and gas.

FAQ's of RTJ End Swing Check Valve:

Q: How does the RTJ End Swing Check Valve prevent backflow in pipelines?

A: The swing check valve employs a disc that swings open to allow flow in one direction and automatically closes when flow reverses, thereby preventing backflow. This mechanism operates solely based on the pressure and movement of the media, ensuring reliable one-way flow without external controls.

Q: What materials are used to manufacture the RTJ End Swing Check Valve and why?

A: The valve body is constructed from ASTM A216 WCB, CF8, CF8M, or equivalent, providing excellent mechanical strength and corrosion resistance. The disc is made from alloy or stainless steel for durability, while seat options include stainless steel or hard-faced alloy for enhanced wear resistance in severe service applications.

Q: When should a metal-to-metal seat be used instead of a soft seat?

A: Metal-to-metal seats are recommended for high-temperature or abrasive service where soft materials may degrade, whereas soft seated options provide tighter sealing for lower-pressure or clean fluid applications. The choice depends on the process media, operating pressure, and temperature conditions.

Q: Where are RTJ End Swing Check Valves typically installed?

A: These valves are commonly used in oil, gas, petrochemical plants, power generation facilities, and water works, particularly in pipelines where reliable prevention of backflow is critical. The RTJ flange connection ensures a secure seal in high-pressure environments.

Q: What testing processes ensure the valve's integrity and performance?

A: Each valve is subjected to hydrostatic and pneumatic testing according to API 598 standards to verify pressure holding capability and leak-tightness before it is dispatched for installation. This guarantees the valve's safe and dependable operation in service.

Q: How is the RTJ End Swing Check Valve installed and maintained?

A: Installation involves bolting the RTJ flanged ends to matching pipeline flanges as per ASME B16.5. Routine inspection is advised, but the valve requires minimal maintenance due to its automatic operation and durable construction. Surface coatings extend service life by resisting corrosion.

Q: What are the main benefits of using this check valve in severe service applications?

A: The primary advantages include reliable backflow prevention, compatibility with aggressive media, minimal maintenance, high pressure and temperature endurance, and a choice of robust materials and coatings. These features make it ideal for demanding industrial processes in India and worldwide.
