High-pressure solenoid valve parameters and explosion-proof instructions

High-pressure solenoid valve parameters and explosion-proof instructions

Release time: 2013-10-16 Origin: Shanghai Xiandie Valve - High pressure solenoid valve

High pressure solenoid valve series - high pressure solenoid valve with explosion-proof

Normally closed: when the coil is energized, the pilot valve core is closed, the pilot hole is opened, the upper chamber pressure is relieved, the piston is pushed by the lower chamber medium pressure, and the solenoid valve is opened; when the coil is powered off, the pilot valve core is reset by the spring, pilot The hole is closed, the upper cavity of the valve is pressurized by the piston orifice and the thrust of the return spring is closed, and the solenoid valve is closed.

Normally open: when the coil is energized, the pilot hole is closed, the upper cavity of the valve is pressurized by the piston throttle hole and the thrust of the return spring is closed, and the solenoid valve is closed. When the coil is de-energized, the pilot valve core is reset by the spring, the pilot hole is opened, the upper chamber of the valve is depressurized, the piston is pushed by the medium pressure of the lower chamber, and the electromagnetic valve is opened.

☆ Principle structure: Step-by-step direct-acting convex-convex piston type; one-step direct-acting guide concave-convex piston type

☆ Note: 1. If the fluid contains impurities, the solenoid valve must be fitted with a filter valve (30-80 mesh/inch) at the inlet end, and there is no solidification and crystallization.

☆ solenoid valve installation position without limit. (S-horizontal, C-vertical)

Explosion-proof coil description:

☆ Explosion-proof solenoid valve is a solenoid valve that works in a more special environment. The user must select the solenoid valve according to the national explosion-proof standard. To ensure the safety of life and property.

☆ High-grade explosion-proof electromagnetic valve (flameproof type)

☆ Explosion-proof mark: EXdIICT5

☆ Explosion-proof shell temperature: ≤95°C

☆ Line size: internal thread M16X1.5 (low power), M22X1.5 (high power)
