2-way zone valve

Description

The valves are made of brass according to criteria of toughness and reliability. The full bore ball shutter guarantees minimum pressure drop and no leakage even after long periods of service. The threaded connections can be female, male or with pipe unions depending on the installation convenience. The 3-way valves have different flow configurations, adapting to the most different types of system situations.
 
The servomotors are equipped with a robust steel gearbox and have a pre-wired multi-core cable for easy electrical connection. De Pala actuators only absorb power during operation, unlike, for example, spring-return servomotors, and have accurate and replicable positioning. 

Thanks to a steel ring on the servomotor and the special manufacturing of the valve body, coupling and uncoupling of the two components is easy, quick and tool-free.

Optionally, the servomotor can be ordered with an auxiliary contact. 
It is a free contact, not under voltage, useful for example to activate the boiler when the valve opens, to remotely signal the open-closed status by a light bulb, or for other functions. On request, De Pala can supply servomotors with two auxiliary contacts, with closed contact when the valve is closed and in other variants.
