The price of stainless steel solenoid valve | Stainless Steel Solenoid Valve Size | stainless steel solenoid valve principle | the role of stainless steel solenoid valve solenoid valve history, so far from home and abroad, stainless steel solenoid valve principle is divided into three categories (ie: direct-acting step by step direct acting, pilot), and from the valve on the different structures and materials with the principle difference between the branch is divided into six subclasses (direct-acting diaphragm structure, step by step membrane structure, membrane pilot sheet structure, direct-acting piston structure, step by step piston structure of the pilot piston structure). (A), stainless steel solenoid valve direct-acting principle:, solenoid coil generates electromagnetic force from the seat to lift the pieces off, valve open; power, the electromagnetic force disappears, the spring force to close the piece down on the seat on the valve closes. Features: In a vacuum, negative pressure, zero pressure can work, but the general diameter of not more than 25mm. (B), stainless steel step direct-acting solenoid valve principle: it is a direct-acting and pilot-a combination of theory, when the inlet and outlet pressure ≤ 0.05Mpa, energized, the electromagnetic force directly to the small pilot valve and main valve closure member in turn lift the valve open. When the inlet and outlet pressure> 0.05Mpa, energized, the electromagnetic force to open the first small pilot valve, main valve chamber under increased pressure, the chamber pressure drops, thus the use of pressure to open up the main valve; off, the pilot valve and the main valve spring force or the use of medium pressure push off pieces, moving down, the valve closed. (C), stainless steel solenoid pilot valve principle: electricity, the electromagnetic force open the pilot hole, the chamber pressure to drop rapidly in close formation on the lower piece around the high pressure, push the closure member to move up, the valve opens; energized, the spring forces the pilot hole is closed, the inlet pressure by-pass rapidly into the hole on the chamber around the valves in the closed form under high pressure on the lower, push off pieces down, close the valve. Ordering process customers as the product has special requirements to be in the contract provides the following instructions: a) length of the structure b) connection form c) nominal diameter, full bore, reduced bore, pipe size d) the use of medium and temperature and pressure range e) testing, inspection standards and other
