The ANSI Industrial Gate Valve is a WCB carbon steel rising stem flange valve. The valve body is made of WCB carbon steel (ASTM A216 standard), the stem is made of alloy structural steel, and the sealing surface is hard alloy weld overlay. It features a rising stem design (the stem rises and falls with the opening and closing action), a blue three-spoke handwheel at the top, and ANSI B16.5 standard flange connections at both ends. The valve cover is bolted. The ANSI Industrial Gate Valve is a core opening and closing element in low-pressure industrial pipelines.

Advantages

High Adaptability

WCB carbon steel construction with Class 150 pressure rating, meeting the media (water, oil, air, etc.) and pressure requirements of most medium and low-pressure industrial pipelines;

High Flow Efficiency

Straight-through flow channel design reduces media flow resistance significantly lower than gate valves, making it suitable for high-flow-rate pipelines;

Status Visualization

The rising stem structure allows direct identification of the valve's open/closed status via the stem position, facilitating on-site inspections;

Low Maintenance Costs

Bolted valve cover allows for easy replacement of seals/gates without requiring complete valve replacement.

Features

American Standard

Complies with ANSI/API industrial specifications, suitable for piping systems in foreign-invested projects and North American export equipment;

Hard Seal Structure

Metal-to-metal seal, resistant to medium-temperature conditions (-20℃~425℃), long seal life;

Anti-corrosion Coating

The valve body uses gray anti-corrosion paint to enhance rust prevention in humid industrial environments.

Application Scenarios

Mainly used for high-flow pipelines carrying medium and low-pressure common media:

Industrial circulating water systems

Opening and closing control of factory cooling water pipelines;

Oil transportation pipelines

Transportation pipelines for common oils such as diesel and lubricating oil;

Municipal engineering

Main fire-fighting water pipelines for large buildings;

General equipment

Inlet and outlet pipeline cutoff for compressors and pump sets.

Production Process

Valve Body Casting

WCB carbon steel is cast using sand casting and then annealed to relieve internal stress.

Machining

The valve body flow channel and flange sealing surface are machined on a CNC lathe, and the sealing surfaces of the gate/seat are machined on a milling machine.

Sealing Surface Treatment

Hard alloy (such as Stellite alloy) is welded onto the gate and valve seat, and then ground to a high-precision fit.

Assembly

The gate, valve stem, packing, and valve cover are assembled sequentially. After tightening the bolts, the handwheel opening and closing torque is adjusted.

Inspection

Pressure tests (shell test and sealing test) are performed to ensure no leakage before spraying anti-corrosion paint, marking, and warehousing.

Routine Maintenance

Routine Inspection

Weekly check valve stem for rust, ensure smooth handwheel operation, and record valve opening and closing status;

Packing Maintenance

Inspect the stuffing box every 3 months. If minor leakage is found, tighten the packing gland bolts appropriately;

Sealing Surface Inspection

Disassemble the valve cover annually to inspect the wear of the gate/seat sealing surfaces. If wear is severe, grind or replace the valve;

Rust Prevention Treatment

For valves that have been out of service for a long period, close the valve and release the medium. Apply anti-rust grease to the valve stem and cover the handwheel with dust.

FAQ

Q: 1. Can this gate valve be used in steam pipelines?

A: Yes, but the operating temperature must not exceed 425℃ (the upper limit of the allowable temperature for WCB carbon steel), and the sealing surface must be checked for wear regularly.

Q: 2. Can the rising stem gate valve be installed vertically?

A: Yes, but ensure sufficient space for handwheel operation, and provide dust protection for the top of the valve stem.

Q: 3. How does your company control product quality?

A: We have an experienced team of experts responsible for inspecting every stage of production. Products are tested at the factory before shipment.

Q: 4. What payment methods does your company currently accept?

A: We accept Western Union, wire transfer (T/T), documents against payment (D/P), documents against acceptance (D/C), and irrevocable letters of credit (L/C).

Q: 5. Can we become your company's distributor in my country?

A: Of course! If you are interested in becoming our agent, we will discuss further.

Q: 6.How can I track the production progress of my order?

A: We will arrange for personnel to take photos or videos of the production process weekly so you can stay informed about the production status. After the goods are completed, we will take detailed photos or videos for your inspection. Once you confirm, we will arrange shipment. Furthermore, you can arrange Factory Acceptance Testing (FAT) upon arrival at our factory.

Q: 7. What services does your company provide before placing an order?

A: 1) We will provide corresponding samples according to your company's needs.
2) After your company inspects the samples, we will provide a quotation.
3) Finally, we will reach an agreement on payment methods, delivery time, packaging, transportation, etc.

Q: 8. What is your company's after-sales service like?

A: We have a dedicated after-sales service hotline. You can call or send an email to inquire about related issues. You can also contact us online to resolve any problems.
