DIN3352 F4 Metal Seat Gate Valve (R.S.) PN10/PN16

Description

The DIN3352 F4 Gate Valve is a high-performance, non-rising stem (NRS) valve engineered for robust flow control in demanding industrial and municipal water systems. Featuring a compact face-to-face dimension (DIN3202 F4/EN558-1 Series 14), this valve is designed for space-efficient installation without compromising structural integrity or sealing performance.

Key Features & Benefits

• Precision Engineering: Manufactured in strict accordance with DIN 3352 standards, ensuring global compatibility and reliable operation.

• Superior Durability: Constructed with a high-strength Ductile Iron (GGG40/GGG50) body, providing excellent resistance to pressure and impact.

• Optimal Sealing: Equipped with an EPDM/NBR encapsulated wedge that ensures a drop-tight, leak-proof seal. The smooth, obstruction-free flow path minimizes pressure loss and prevents the buildup of impurities.

• Corrosion Resistance: Internally and externally coated with high-quality Fusion Bonded Epoxy (FBE), making it ideal for sewage, treated water, and industrial chemical applications.

• Reliable Operation: The non-rising stem design provides a stable, low-torque operation, making it the preferred choice for underground installations and systems where space is limited.
