STANDARD SPECIFICATIONS
ROSS’ new SERPAR ® Crossflow Double Valves with Dual
Monitoring provide the reliability and durability you have come to
expect from ROSS since the introduction of the first monitored double
valves for mechanical power press safety in 1954.
These dual-monitored valves are based on the proven technology
of the SERPAR ® Crossflow family of double valves, adding independent
signal sources and redundant monitoring to meet CSA Z142 (Cana-
dian Standards Association) requirements for safety circuit performance.
Incorporating both ROSS’ L-G and E-P monitoring systems provides
redundancy in monitoring through two separate, dissimilar monitors.
The actuating solenoids are wired independently through a double-
pole, double-throw switch in the E-P monitor.
These new SERPAR ® Crossflow Double Valves with Dual
Monitoring are available in sizes 8, 12, and 30, with port sizes ranging
from 1/2 to 2. The valves mount inline via removable flanges, and are
available with or without manual overrides.
