Zone Valves and Actuators

The Zone Valves VZ-series and Actuators AZ-series to be applied in hot and chilled applications.

The Zone Valves VZ-series are available in 2-way, 3-way and 3-way with 4 port with the sizes DN15 and DN20 (1/2" and 3/4") and Kvs values 0.25, 0.4, 0.6, 1.0, 1.6, 2.5, 4.0 and 6.0.

Actuators AZ-series have actuating force 140 N with control signals on/off ,
PWM (Pulse With Modulation ) or 0-10 Vdc.

Zone Valves VZ-series and Actuators AZ-series are both Normally Closed (NC) and both valves and actuators have stroke lenght 2.5 mm and the actuators are equipped with a yellow stroke indicator.

Fast and easy assembling of AZ actuator on VZ zone valve with a threaded ring nut.

Features

Zone Valves:

? 2-way, 3-way and 3-way 4-port valves

? Sizes DN15 and DN20 (1/2" and 3/4")

? Kvs values from 0.25 up to 6.0

? Brass valve body

? Operating pressure 16 Bar

? Stainless steel stem

? Stroke length 2.5 mm

? Stem tight double OR ring in EPDM

? Seat in technopolymer

? Threaded male collar M30x1.5 for fitting of actuator

? All VZ-valves are Normally Closed (NC),
i.e. the action of the valve spring makes the plug
move to the upper seat, even with disassembled actuator.

Actuators:

? AZ-series actuators to be used with
VZ-series DN15 and DN20 (1/2" and 3/4") valves
with kvs value from 0.25 up to to 6.0

? Actuating force 140 N

? Control Signals
On/Off , PWM (Pulse With Modulation ) or 0-10 Vdc

? Normally Closed (NC)

? Stroke length 2.5 mm

? Position indicator

? Fast and easy assembling of actuator on valve with a threaded ring nut

? The ring nut M30x1.50 suppiled with the actuator
(Threaded ring nut for other valve brands on request)

? Compact design

? Supplied with 2 meter cable

? Precise control of valves

? Applied in hot and chilled applications
