About ASME B16.34 Globe Valve

ASME B16.34 Globe 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 Connection Options

ASME B16.34 Globe Valves support flanged, butt weld, socket weld, and threaded end connections, offering flexibility for installation in new setups or retrofitting existing pipelines. This adaptability ensures seamless integration into a diverse range of industrial systems and optimizes operational compatibility.

Rigorous Quality and Compliance

Manufactured to ASME B16.34 standards, each valve undergoes stringent pressure and leakage tests per API 598 and ISO 5208. These robust testing measures assure end-users of consistent, leak-tight, and reliable operation, even in demanding conditions involving water, oil, gas, or steam.

Customizable Operation and Sealing

Operators can choose from manual handwheel, gear operators, or actuators (pneumatic/electric) to suit their automation requirements. Metal and soft seating options offer tailored sealing performance, supporting media-specific needs and leakage class compliance for critical applications.

FAQs of ASME B16.34 Globe Valve:

Q: How can I select the suitable end connection for my ASME B16.34 Globe Valve?

A: Begin by evaluating your pipeline setup and installation requirements. The valve comes with flanged, butt weld, socket weld, or threaded end connections. Flanged is often chosen for ease of maintenance, while butt weld and socket weld provide permanent leak-free joints. Threaded ends are suitable for low-pressure systems and faster installation.

Q: What benefits do rising stem and OS&Y design features provide?

A: The rising stem and Outside Screw & Yoke (OS&Y) design allow visible stem position indication, improving operational safety and facilitating valve status checks. These features also enhance the durability and reliability of valve performance in demanding environments.

Q: When is it advisable to use a metal-seated versus a soft-seated globe valve?

A: Metal-seated globe valves are ideal for high-temperature, high-pressure, or abrasive applications, offering enhanced durability. Soft-seated valves provide superior sealing for low-leakage requirements, typically in lower temperature and pressure settings where tight shut-off is critical.

Q: Where are ASME B16.34 Globe Valves typically used?

A: These valves serve across a spectrum of industrial sectors, including oil & gas, petrochemical, power generation, water treatment, and general industrial process pipelines. Their versatile design makes them suitable for controlling flow in challenging media such as water, oil, gas, and steam.

Q: What is the process for installing and maintaining this globe valve?

A: Installation depends on the selected end connection and pipeline configuration. Generally, it requires proper alignment, sealing, and bolt tightening as per ASME and manufacturer recommendations. Routine maintenance includes checking for leaks, lubricating moving parts, and inspecting for wear, particularly at the seat and packing.

Q: What are the advantages of valves tested per API 598 and ISO 5208?

A: Valves tested to these standards undergo thorough pressure and leakage assessments, guaranteeing high integrity, operational reliability, and compliance with international performance criteria. This translates to safer and longer-lasting operation in critical service conditions.
