The goods must be checked on completeness and transport damage. See also section 9.0
3.2 Storage
If the valve is not installed immediately after delivery, it must be stored properly.
Storage temperature -20°C up to + 60°C, dry and clean.
The lacquering protects against corrosion in neutral dry atmosphere. Do not damage colour.
In humid rooms, a drying agent or a heating resp. is necessary because of condensation of
water.
Requirements according to DIN 7716 (products made of caoutchouc and rubber) must be met.
3.3
Handling before mounting
In case of valve with protection caps, they must be removed before being mounted!
Protect against atmospheric influences such as humidity (otherwise use drying agent).
Appropriate treatment protects against damage.
4.0 Product
Description
The UNI-Geräte Electro – solenoid valve EVS is a directly controlled, currentless closed safety shut-off
valve acc. to DIN EN 13611, DIN 3394-1 and DIN EN 161 (DIN EN 264) with solenoid drive.
Sectional drawing 11.1 Fig. 1 - 4 shows the valve construction.
4.1 Function
By switching on the solenoid drive, the solenoid core (207) is drawn against the upper part (106). The
pressure spring (503) is pressed and the balance piston (220) releases the valve cross section. The
valve is open.
The valve closes by switching off, interruption or failure of power energy to solenoid drive. Due to
press of the pressure spring (503) the balance piston closes (220). The valve is closed at 15% of
nominal voltage.
