BOSCH REXROTH Z2FS 10-5-33/ R900989095

Rexroth Double Throttle Check Valve NG10

Description

The Bosch Rexroth Z2FS 10-5-33/ is a high-performance double throttle check valve in a sandwich plate design. It is used to limit the main or pilot flow of one or two actuator ports. This is achieved by throttling the flow in one direction and allowing free flow in the return direction. Its robust construction ensures long-term reliability in demanding industrial hydraulic applications.

FAQ

What is the primary function of a double throttle check valve?

Its main function is to control the speed of a hydraulic actuator (like a cylinder) by restricting the fluid flow rate to or from the actuator. It throttles the flow in one direction and allows unrestricted flow in the opposite direction, enabling ‘meter-in’ or ‘meter-out’ control circuits.

What does the NG10 designation mean for this Rexroth valve?

NG10 (Nominal Size 10) refers to the valve’s porting pattern, which complies with international standards such as ISO 4401-05 and CETOP 5. This standardization ensures that the valve can be mounted on any corresponding subplate or stacked with other NG10 valves from various manufacturers.

How can I identify the date of manufacture for this valve?

The date of manufacture is indicated by the ‘FD’ (Factory Date) code on the nameplate. For this valve, the code is ’07W34′, which translates to the 34th week of the year 2007.
