Product Application

Hydraulic monoblock valve is controlling component of the hydraulic system,which is used for adjusting  the direction,pressure and flow.The valve is widely used in the hydraulic system of forklift,sanitation vehicle and light loading machines.Comparing the sectional control valve,monoblock valve's biggest advantage is excellent sealing 

performance.Also it has a smaller volume，which is suitable for the appilication scene where requires high flow.

Main Features

ZDa: product series;
L: thread connection, the size is G1/2;
15: the diameter, corresponding flow is 60L/min;
F: working pressure, 20mpa;（H: working pressure 31mpa）
2: means 2 working spool;（1~7 spools）
O: Spool funtion(when the valve is in neutral position, the oil is circulated back into the tank)
T: spring return;(W:Ball locking)
