Pilot Oil Source, Pilot Control Valve Block for Excavator

XDYY Pilot Oil Source
Application 
This product is applied to the control circuit of a hydraulic system and changes the flow direction of oil line through the solenoid directional valve so as to meet the requirements on working conditions of the system. This kind of valves is widely used by all types of excavators, construction machinery, minning machinery, farm machinery. 
 
Functions and features 

1. Thread cartridge solenoid valve, check valve and accumulator contribute to a compact structure and easy maintenance; 
2. A check valve is added at the oil inlet to maintain the pressure of the whole control circuit and also avoid shock of system press from control circuit to the control pump. 
3. Accumulators can be used to ensure pilot pressure stable; 
4. Spool can provide different matching range according to customer requirements; 
5. The modular design; 
6. Functions of valve manifolds can be extended according to customer requirements.  

Basic parameters 
 
1. Rated working pressure: 4MPa
2. Rated flow: 20L/min
3. Rated working voltage: 24V DC
4. Accumulator capacity: 0.25L; inflation pressure: 1.5MPa

Potassium Sorbate is the potassium salt of sorbic acid,chemical formula CH3CH=CH−CH=CH−CO2K. It is a white salt that is very soluble in water (58.2% at 20 Â°C). It is primarily used as a food preservative(E number202 ).Potassium sorbate is effective in a variety of applications including food,wine,and personal-care products.While sorbic acid is naturally occurring in some berries, virtually all of the world's production of sorbic acid, from which potassium sorbate is derived, is manufactured synthetically.Potassium sorbate is used to inhibit molds and yeasts  in many foods, such as cheese,wine,yogurt,dried meats,apple  cider,soft drinks and fruit drinks, and baked goods. It can also be found in the ingredients list of many dried fruit products. In addition, herbal dietary supplement products generally contain potassium sorbate, which acts to prevent mold and microbes and to increase shelf life.
