BNT Manual Valves

BNT 631 M is a control valve which manually initiates the backwash cycle via a hand wheel. The backwash cycle includes the backwash as well as the quick rinse, which are each adjusted by turning the hand wheel. The valve requires no electricity and provides safe, reliable and easy operation. A child lock is also built into the control head and thus ensures protection for unwanted operation. The backwash can be done at any time via the hand wheel.
