NIAGARA Butterfly Valve – Model FFSD5DRG

Description

NIAGARA Double Regulating Butterfly Valve – Model FFSD5DRG
This valve is designed for use with BS EN 1092-2 PN16 flanges and built in accordance with BS EN 593.
The Double Regulating feature allows the valve to serve both as an isolating and flow control valve. Once preset, the valve can be reopened to the same position to maintain the desired flow rate, ensuring consistent hydraulic performance in complex piping systems.

The ductile iron body and disc provide durability and resistance to corrosion, while the EPDM liner ensures tight sealing and long service life.
A 420 stainless steel shaft provides superior mechanical strength and smooth operation even under high torque conditions.
