Industrial Check Valves for Export

Check Valves designed for water supply networks, pump stations, and industrial systems. Manufactured from ductile iron, carbon steel, or stainless steel, our valves are tested according to DIN, EN, and ISO international standards and come with epoxy powder coating approved for potable water use.

Types of Check Valves

1. Tilting Disk Check Valve (شیر یکطرفه وزنه‌ای)

• Size Range (DN): 150–2000 mm
• Pressure Rating (PN): 10–40 bar
• Applications: Water supply networks, pumping stations, and non-corrosive fluids up to 70°C

Tilting disk check valves feature adjustable opening/closing speed, a lever position indicator, fast closing action, low-pressure drop, and stainless steel sealing rings. They are ideal for large pumping stations where flow monitoring is critical.

2. Swing Check Valve (شیر یکطرفه دریچه‌ای)

• Size Range (DN): 50–300 mm
• Pressure Rating (PN): 10–16 bar
• Applications: Pipelines with low fluid velocity

Swing check valves offer very low turbulence, minimal pressure drop, and can be installed horizontally or vertically. They are a cost-effective solution for small and medium pipelines.

3. Spring Type Piston Check Valve – Short Body (شیر یکطرفه سوپاپی فنردار – بدنه کوتاه)

• Size Range (DN): 50–500 mm
• Pressure Rating (PN): 6–40 bar
• Applications: Pump suction/discharge lines, secondary system connections

These valves provide fast spring-assisted closure, reduced water hammer, compact design, and easy maintenance. They are suitable for modern pumping systems where space and performance are essential.

4. Spring Type Piston Check Valve – Full Range (شیر یکطرفه سوپاپی فنردار)

• Size Range (DN): 50–2000 mm
• Pressure Rating (PN): 6–40 bar
• Applications: Large pipelines, industrial systems, pump protection

This type covers a wider size range and is ideal for high-capacity pipelines. It ensures fast closure, reliable backflow prevention, and is available with optional full stainless-steel construction for aggressive environments.
