Sale of shut-off and control valves for pipelines: ball valves, gate valves, check valves, and filters according to ASME standards. Wide product range and professional consultation for proper selection. ASME shut-off valves are designed to stop, regulate, and direct the flow of liquids and gases in pipeline systems. They ensure tight sealing and stable operation of pipelines even under high pressure, temperature fluctuations, and exposure to aggressive environments. The catalog includes ASME B16.34 gate valves, ball valves, strainers, and check valves manufactured from corrosion-resistant steels and alloys such as Incoloy, Hastelloy, and Alloy grades, ensuring long service life and full compliance with international standards. Equipment certified according to ASME, API, and EN standards is widely used in the oil and gas, chemical, power generation, and petrochemical industries.

Which ASME shut-off valves are required for pipelines?

The selection of ASME valves depends on operating parameters such as pressure, temperature, and the chemical composition of the transported medium:

- for aggressive or high-temperature environments, products made of stainless or alloy steel (e.g., ASTM A351 CF8/CF8M, ASTM A216 WCB) are recommended to ensure corrosion resistance;

- for reliable shut-off, ASME B16.34 wedge gate valves are commonly used;

- for flow regulation, ASME B16.10 ball valves are applied;

- to protect the pipeline from reverse flow, ASME check valves are installed.

The selection of shut-off valves is carried out strictly in accordance with operating conditions and international industrial standards.

Installation and mounting of ASME valves

Installation of ASME shut-off valves requires strict adherence to installation procedures and proper sealing of connections. Depending on the valve design, welded, flanged (ASME B16.5), or threaded connections are used.

During installation, the following aspects must be controlled:

- correct orientation of valve components,

- tightness of sealing elements,

- absence of mechanical damage.

Proper installation of products compliant with ASME and ASTM standards ensures the reliability of the pipeline system, extends equipment service life, and reduces the risk of operational failures.

FAQ

1. Which sealing materials are best suited for aggressive environments?

Fluoropolymers (PTFE), graphite, and chemically resistant elastomers capable of withstanding temperature fluctuations.

2. How does the frequency of operating cycles affect valve selection?

Ball valves generally withstand a greater number of opening and closing cycles compared with wedge gate valves.

3. How does medium viscosity influence valve selection?

Viscosity determines the required bore diameter and the appropriate method of flow regulation.

Comments

1. Which valves should be used in pipelines with rapid pressure fluctuations?

Reinforced wedge gate valves with durable bodies and adjustable sealing elements are typically recommended.

2. How should the valve diameter be selected correctly?

It should be selected according to the design flow rate of the medium and the allowable pressure losses in the pipeline.

3. Can different types of valves be combined within the same pipeline line?

Yes, provided that hydraulic characteristics and sealing requirements of the system are properly considered.
