TRM series multi-way valve has good quality from Shandong Taifeng Hydraulic

Multi-way directional valve
Series multi-way directional valve
1
Overview
r series multi-way directional valve is currently the most advanced type of valve introduced, digested and absorbed at home and abroad. A hydraulic control component developed with advanced technology. r Can replace German Rexroth . This series of products has the characteristics of small size, load sensitivity, energy saving, precise and sensitive operation, controllable working flow, high degree of intensification, easy installation and maintenance, etc. It can completely replace various multi-way reversing valves with the same flow rate currently used in China.
2.
Applicable models of multi-way reversing valve (excavator)
The r series is suitable for excavators with tonnage of 1000 tons and below, such as Yuchai-, Yuchai, Doosan, Lingong, Liu Gong D, Foton Lovol R, Lishi De-, Shanhe Intelligent, Lonking D/, Kaiyuan/ and other multi-way directional valves with the same flow rate.

Product Features
. Provide the highest pressure and flow required for work through load pressure feedback. Significantly save energy and effectively protect the entire system and maximize the use of system power.
.The application of differential pressure valve makes the flow rate of each working port not affected by the load, and the flow rate of different working ports can be set to adapt to the requirements of working conditions, and the action response is sensitive and accurate.
The use of pressure compensator ensures that all working oil ports can work smoothly and simultaneously under low flow conditions.
.The compact chip structure can be arbitrarily combined into corresponding multi-way valves according to different working conditions, significantly improving power density.
.The parallel structure circuit ensures that the actuators act independently without interfering with each other.
.Can be used in various quantitative pump systems and variable pump systems.
.Each working oil port can be equipped with built-in secondary overload valve and oil supply valve respectively for protection and adjustment. The overall height of the entire valve remains the same regardless of whether it is installed or not.
.A variety of control methods are available: manual operation, pilot hydraulic control, electro-hydraulic control and combinations thereof.
.A variety of positioning methods are available: spring return, mechanical positioning, etc.
.A variety of slide valve machines are available for selection and combination: such as,,,,, type and other three- and four-position functions.
