Parker Electronic Valve
Product Bulletin 24-00 B
Purpose:
The PEV series of electronic
modulating valves provide enhanced
control for industrial refrigeration
systems. The PEV provides
precise control of ow for liquid
level, expansion, superheat, and
temperature control applications.
The stainless steel construction
helps overcome corrosion problems
encountered in harsh environments.
The valve's weld-in feature design
reduces potential for connection
leaks.
This design has a higher working
pressure, a greater working
temperature range and higher ow
capacities than competitive products.
These valves provide long-term
performance with replaceable internal
components.
Product Features:
• Suitable for ammonia, CO
2
, R-134a,
R-404a, R-410a and other common
refrigerants
• Stainless steel construction
increases product life cycle
• Lightweight construction
•
Cartridge based design simplies
service and eliminates body wear
•
Interchangeable cartridge assembly
with other P-Series offerings
• Works with any 4-20 mA controller
• Bright Seven-Segment LED Display
• Password protection prevents
tampering
• Alarm notication
• IP67/NEMA 6 rated
• Parker Backup Module (PBM)
