รหัสสินค้า : 418113

รายละเอียดสินค้า

– non-return valve with controlled, non-slam closure

– resilient seal or laminated metal-to-metal seal

– triple offset design with inclined conical sealing system

– adjustable hydraulic damping system, located externally and separated from the media

The RZN has an excellent record of reliability in critical applications where other check valves have failed.

The duo-eccentrically mounted disc is hydrodynamical designed for low pressure loss and freedom from jamming at the seat. The special ADAMS damping system ensures tight and progressive shut-off against reverse flow and offers long service life.

The compact design allows installation in confined spaces. All internal screws on ADAMS non-return valves are mechanically locked.
