Throttle Check Valve Z2FS 6

Huafilter started our export business of Huade® double throttle check valve Z2FS 6, after becoming the agent of Huade Hydraulic in 2023. Huade Hydraulic is the vice chairman unit of China Hydraulic and Pneumatic Seals Industry Association. Huade® throttle check valves are used in many industrial fields. Due to superior performance and low price, their products are sold all over the country and all over the world. Looking for cost-effective hydraulic double throttle check valve, choose Huade®!

Valves type Z 2 FS 6 are double throttle/check valves in sandwich plate design. This valve is suitable for vertical stacking assembly and is used for inlet or outlet meter-out control. As a result of two long-term cooperation with Rexroth, this throttle Z2FS 6 matches Rexroth in performance and can replace Rexroth® Z2FS6 3XB series. It is an affordable alternative for Rexroth.

Product Feature And Application of Throttle Check Valve Z2FS 6

Features:

▶ Sandwich plate design

▶ Porting pattern to DIN 24 340, from A, ISO 4401 and CETOP - RP 121H

▶ Limiting of main or pilot flow with two service ports

▶ Meter-in or meter-out control.


Application:

Throttle check valves Z2FS 6 are used to limit main or pilot oil flow at one or two service ports.

Section and symbol of Throttle Check Valve Z2FS 6

Two symmetrically arranged throttle/check valves limit flow (by means of adjustable throttle spools) in one direction and permit free return flow in the other direction.

Main flow limiting

The double throttle/check valve is fitted between the directional valve and the subplate to change the speed of an actuator (main flow limiting).

Pilot flow limiting

In the case of pilot operated directional valves, the double throttle/check valve may be used as a pilot choke adjustment (pilot flow limiting). In this case, it is fitted between the main valve and the pilot valve.
