21/2" (1 pair - 2 pieces)

Besgo valves are pneumatic valves operated by air or water pressure (tap water). The pilot pressure should be 3 - 5 bar. Sizes DN40 / 1 Ø 2 50 mm to DN125 / 3 Ø 4 140 mm. Ozone resistant. Includes solenoid valve. Besgo valves are supplied without filter connections. Special features: - Highest operating reliability. - The rinse unit opens with water and closes with spring pressure. In the event of a power failure, the Besgo valve automatically returns to the 'Filter' position. - When operating, there is no need to turn off the filter pump. - Low pressure loss. - This results in the shortest possible backwash which is important for a virtually pressure-free backwash system. Technical features: - Housing made of PVC-U. - Internal parts made of stainless steel 316 (1.4571). - Seals: Viton / Teflon. - Actuator closes without pressure, hydraulically simple with spring. - Operating pressure: 3 - 6 bar tap water or compressed air. - Maximum working pressure: 3,5 bar. - The solenoid valve serves to control the hydraulic drive and can be connected to any commercially available control unit. Normally closed. - Electrical connection 230V/50 Hz. * Ask for availability.
