800 Series Valve

The 800 series piston actuated valves are hydraulically operated globe valves in either the standard oblique (Y) or angle pattern design. Using this piston means that no diaphragm is required and the unit remains extremely reliable, even under high pressure. The design ensures that cavitation is reduced and, pressure loss is up to 30% less than from other control valves. The valve meets the requirements for drinking water distribution on an urban scale and in buildings, wastewater, fire protection systems, industry and water flows in general. The valve comprises two major components: the body seat assembly and the actuator assembly. The actuator assembly is unitized and is removable from the body as an integral unit. It consists of both an upper and a lower control chamber. Due to this design the valve is maintenance friendly and can be done without removing the unit from the installation. We can advise you based on the required flow rate, functions, quality approvals and applications.
