General Description
A Control Valve B
Dual Cross-Over Relief Valve with
RVA
Motor Mount. This valve provides

Valves
SH overload and shock protection for
small gerotor motors with a manifold
mounting pattern, such as the Parker TB
and TE series. Close coupling the valve to the motor
provides ideal protection and eliminates plumbing. RVB

Features
Load/Motor
Controls
FC • Fast acting differential area reliefs for high flow capacity RVB
• Spherical poppets for low leakage
• Internal mechanical stop limits poppet travel eliminating RVA
spring solidification
Flow
Controls
PC • “D”-Ring eliminates backup rings
• All external parts have yellow zinc dichromate. This RDH103 Series
coating is ideal for salt spray applications. Relief Cartridge Valve (2 Ea.) Body
