Terminal valve STVT is used for adjustment and measurement in heating and cooling systems.
STVT is an adjustment and control valve with presetting.
The valve is equipped with self-sealing measuring ports, placed at a 45° degree angle in relation to the actuator.
Pre-setting can be carried out using the pre-setting key FN2.
STVT comes with external and internal thread 1/2″ and 3/4″.
The valve can be used with actuator or thermostatic head with M28x1,5 connection.
Min measurable differential pressure
Recommended pressure drop at dimentsioning valve
Kv-value (pre-set) with actuator
DN15 0,01 2,15
DN20 0,01 – 2,80
Kvs-value (maximum capacity)
DN 15 2,15
DN 20 2,80
Pre-setting FN2 key
The valves are equipped with a insert with concealed pre-setting.
Pre-setting can be done with the FN2 tool by turning the number of turns as shown in the pressure drop diagram.
To simplify this process use the pre-setting tool FV18 and FV19.
Pre-setting tool FV18 and FV19
Pre-setting tool FV18 is used for STVT DN15 and FV19 for STVT DN20.
