V37-100A Series

Design and PerformanceFeatures:. High capacity pilot-operated

system relief valve with manyparts common to all valvemodels.

. SAE 4- bolt porting for highpressure systems. SAE straightthread ports available in singleplunger units. Top inlet and outletplugged but available for use.

. Standardized detent design withmany parts common amongvarious detent styles reducingservice parts requirements.Detent Kits available, for moreinformation contact factory.

. Housings are machined to take highpressure carry-over kit (Kit no.SKO 151 provides 1 1/4-4-boltport- split flange ported units only).

. Hollow plunger constructionwith built-in load hold checks for

precise metering.

Performance Data

Performance tests with oil temperature120° F (4go C) - viscosity 173-185 SSUat 100° F (37.7° C).

Pilot-operated ReliefRelief valve is adjustable from0-2500 psi (0-172 bar) and canbe installed in either side of valve(same side as "8" cylinder ports isstandard location).
