HY-TEGRA MANIFOLD-MOUNTED TYPE BALANCING VALVE（HGR2M）■FeaturesThis is a balancing valve that can be mounted on the HY-TEGRA manifold. This
compound pressure control valve supplies any balancing pressure required to ensure
the smooth vertical motion of a large load such as a spindle head. It can control thecompound function that provides the combination of the pressure reducing valvefunction and the relief valve function to allow controlling of balancing pressure with asingle adjusting screw.
1. Since the valve provides compound functions, the hydraulic system can be madecompact.
2. Pressure adjustment is simple, using only one adjusting screw.
●There are two types of valve differing in their type of drain: internal drain or external drain.
