DualPlateCheckValve NBRSeat

This dualplate wafertype check valve with NBR (nitrile rubber) seats offers efficient nonreturn protection in compact installations. With two springloaded plates mounted in a streamlined body, it ensures rapid closure, low head loss and minimal footprint.

Technical Data:

• Body Material: Epoxy Coated Ductile Iron Body, Epoxy Coated Carbon Steel Plates 1½" to 8", Ductile Iron Plates 10" to 24"
• Seat Material: NBR for seamless sealing in water, glycol or mild fluid systems, temperature up to ~100°C.
• Design: Wafer pattern to fit between companion flanges, reducing length and installation cost.
• Pressure Rating: PN10 (~10bar)
• Operating Temperature: 10°C to +100°C typical for NBRseat versions.
• Key Mechanism: Dual springloaded plates reduce slam and waterhammer compared to singledisc swing checks.

Key Features:

• Compact wafer design simplifies retrofit or tightspace installations.
• Dual plate and spring design delivers faster shutoff and more stable nonreturn performance.
• NBR seat ensures good sealing for water applications at moderate temperatures.
• Lightweight body and quick installation save time and cost.

Typical Use Cases:
Commercial HVAC systems, building services water circuits, irrigation feed lines, general nonreturn tasks in water and light fluid systems.
