Structural features:
Pilot-type structure, with a stainless steel piston as the valve core;
High sealing performance and long service life;
There is no direct friction between the piston and the metal valve chamber;
Special large-power coil, less prone to burning out, and still sensitive during long-term operation;
Zero leakage, with a service life of over 100,000 times;
Working principle:
Normally closed type: When the coil is energized, the pilot valve core is attracted, the pilot hole opens, the upper chamber of the valve is relieved of pressure, and the piston is pushed by the medium pressure in the lower chamber, and the electromagnetic valve opens; when the coil is de-energized, the pilot valve core is reset by the spring, the pilot hole closes, the upper chamber of the valve is pressurized by the piston throttling hole and the push force of the reset spring, and the electromagnetic valve closes.
Normally open type: When the coil is energized, the pilot hole is closed, the upper chamber of the valve is pressurized by the piston throttling hole and the push force of the reset spring, and the electromagnetic valve closes; when the coil is de-energized, the pilot valve core is reset by the spring, the pilot hole opens, the upper chamber of the valve is relieved of pressure, and the piston is pushed by the medium pressure in the lower chamber, and the electromagnetic valve opens.
Note:
1. The outlet end has a higher pressure than the inlet end. The medium will reverse and conduct. A check valve can be installed or a valve with built-in check function can be customized.
2. Before stopping the use of the electromagnetic valve, the internal residual medium of the valve must be cleaned.
Product application:
It is widely used in the automatic control systems of pipelines for media with high viscosity (greater than 50 Cst) in industries such as metallurgy, petrochemicals, pharmaceuticals, tobacco, food and medical care, scientific research, energy conservation, and gel production.
Packing of Standard Packing:
Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 470 gallon liquid totes Special package is available on request. E FORUs’ is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
