EVRA / EVRAT
EVRA is a direct or servo operated solenoid valve for liquid, suction and hot gas lines with ammonia or fluorinated refrigerants.EVRA valves are supplied complete or as separate components, i.e. valve body, coil and flanges can be ordered separately.
EVRAT is an assisted lift, servo operated solenoid valve for liquid, suction and hot gas lines with ammonia and fluorinated refrigerants.
EVRAT is specially designed to open - and stay open - at a pressure drop of 0 bar. The EVRAT solenoid valve is thus suitable for use in all plant where the required opening differential pressure is 0 bar.
EVRAT is available as components, i.e. valve body, flanges and coil must be ordered separately. EVRAT 10, 15 and 20 all have spindle for manual operation.&w=1920&q=75)
EVRB
EVRB block valve incorporates few functions in one housing, which can replace a series of conventional mechanical and electromechanically operated valves.
This valve station not only provides a number of advantages in the design phase of a refrigeration plant but also in the installation, service and maintenance.
The EVRB block valves are designed for oil lines with some concentration of refrigerants. Supplied as a complete assembly, it is fully tested at high pressure and its functions are tested under factory controlled conditions.
EVRS / EVRST
EVRS and EVRST are valves made of stainless steel.
- EVRS 3 is direct operated
- EVRS 10, 15 and 20 are servo operated
- EVRST 10,15 and 20 are forced servo operated
The valves are used in liquid, suction, hot gas and oil return lines with ammonia or fluorinated refrigerants.
EVRS 3 and EVRST are designed for keeping open at a pressure drop of 0 bar.
EVRS/EVRST 10, 15 and 20 are equipped with spindel for manual opening.
EVRS and EVRST are supplied as components, i.e. valve body and coil must be separately ordered.
