Ball valve, fine adjustment, nickel-plated/bright brass, Rp 1/4 to Rp 2, DN 8 to 50 - Riegler

The ball valve with fine adjustment and Rp 1/4 to Rp 2 connection opens and closes the line in fine steps via a handwheel. Available connections: Rp 1/4, Rp 3/8, Rp 1/2, Rp 3/4, Rp 1, Rp 1 1/4, Rp 1 1/2, Rp 2. It complies with EN 13828 and DVGW worksheet W 570 and is therefore approved for drinking water. Unlike a plain on/off ball valve, this model opens and closes in fine steps via a spindle, so the flow can be set precisely and pressure surges are avoided. A scale on the handwheel shows the ball position.
