Stainless Steel Vertical Check Valve Full Bore 1/4" To 4"

Description of Stainless Steel Threaded Check Valve

The LIANHE Stainless Steel Threaded Check Valve is designed to provide reliable backflow prevention and stable fluid control in industrial and commercial piping systems. The valve automatically opens when the upstream pressure reaches the required level and closes when the flow stops or reverses, helping protect pumps, pipelines, and other system equipment from reverse-flow damage.

Manufactured using precision investment casting and CNC machining, the valve provides good structural strength, accurate dimensions, dependable sealing, and consistent operating performance. Its compact threaded design allows it to be installed easily in restricted pipeline spaces while simplifying maintenance and replacement.

The full-bore flow passage helps reduce pressure loss and flow resistance, improving the operating efficiency of the piping system. Stainless steel construction also provides excellent resistance to corrosion, moisture, and a wide range of compatible fluids, making the valve suitable for demanding working environments.

Technical Specifications

Our stainless steel threaded check valves are available in different sizes, thread standards, materials, and structural configurations to meet various pipeline and engineering requirements.

The exact operating pressure, temperature range, thread standard, sealing material, and installation direction should be confirmed according to the selected valve model and actual pipeline conditions.

Typical Applications

This stainless steel check valve can be used in a wide variety of fluid-control and pipeline applications, including:

• Building water supply and drainage systems

• Industrial water-treatment equipment

• Refrigeration and cooling systems

• Fuel-gas and compatible gas pipelines

• Food and beverage processing equipment

• Medical and sanitary facility pipelines

• Environmental protection equipment

• Chemical-processing systems

• Pump outlets and pressure-control systems

• Oil, water, and general industrial fluid pipelines

Before installation, customers should confirm the compatibility of the valve-body material, sealing components, pressure rating, temperature range, and process medium.

Packaging, Shipping and Payment

Standard Export Packaging

Each valve is protected with a plastic bag to reduce exposure to moisture and dust. The products are then packed in reinforced cartons and consolidated in wooden cases or on export pallets when required.

This multilayer packaging method helps prevent impact, contamination, and surface damage during handling and international transportation. Customized packaging, private labels, barcodes, and customer logos can also be provided according to order requirements.

Payment Terms

The standard payment term is a 30% T/T deposit, with the remaining 70% balance paid before shipment. L/C at sight may also be accepted for qualified orders. Western Union, PayPal, and other payment arrangements can be discussed according to the order value and cooperation conditions.

Shipping Terms

Available international trade terms include EXW, FOB, CFR, and CIF. Transportation can be arranged by sea, air, land, or international express service according to the order quantity, destination, delivery schedule, and customer preference.

Free Samples

Free samples may be provided for product testing, dimensional verification, and quality evaluation. The sample itself can be supplied free of charge, while the express delivery cost is normally paid by the recipient.
