Rexroth NG10 Hydraulic Throttle Check Valve

Description

This is a Z2FSK 10-2-12/2QV sandwich plate throttle check valve from Bosch Rexroth. It is designed for mounting in vertical stacking assemblies to limit the main or pilot flow of one or two actuator ports. This NG10 (CETOP 05) valve provides reliable and precise speed control for hydraulic actuators by throttling the flow in one direction and allowing free flow in the opposite direction.

FAQ

What does the '2Q' in the type code Z2FSK 10-2-12/2QV signify?

The '2Q' refers to the hydraulic circuit symbol. It indicates a double throttle-check valve with throttling in the meter-out direction for both service ports A and B, typically used for controlling the speed of a hydraulic actuator in both directions.

This valve uses the NG10 (also known as CETOP 05 or D05) mounting pattern, which conforms to ISO 4401-05-04-0-05 and DIN 24340 Form A standards. This ensures compatibility with other standard NG10 subplates and valves.

The 'V' indicates that the valve is fitted with FKM (Viton) seals. These seals are suitable for use with mineral oils (HL, HLP), synthetic fluids (HFD), and have excellent high-temperature resistance, but they are not recommended for use with glycol-based fluids or hot water.
