UW-20 2W200-20 3/4'' NBR Diaphragm Uni-d Type Water Air Oil Solenoid Valve Normally Closed DC12V AC110V

The shown solenoid valve is one of our brass solenoid valve; this UW-20 solenoid valve's port size is 3/4''; the valve type of this 2/2 way brass solenoid valve is normally closed; Available mediums are water, air oil, gas, fuel and so on; standard voltages are DC12V, DC24V, AC110V, AC220V; the diaphragm common used is NBR, and Viton is also available. Followings are main features of this solenoid valve:

Stable Coil

Good insulation performance and good heat dissipation

Brass Valve Body

Copper valve body achieve good heat dissipation and long service life.Fine processing fulfills a smooth thread and each port is protected by thread cap

Flow Direction Mark

Each port is with dust cap and each valve base is marked with the flow direction.

Installation

Can be installed at any angle, but it is a good choice when the horizontal tube keep upward.

Application

Used to control automatically the liquid and gas in the pipeline.

Install and use attentions:

When install the solenoid valve,medium flow diretion must be consistent with the direction arrow as shown in the valve body, the valve must be installed in horizontal pipe runs. Solenoid valve coil keep in a vertical position, the valve can not be put in these places what with the splashing water or water leakage. (The 2A models can be used in the under water enviroment.)

Before installing the solenoid valve, pipeline should be cleaned thoroughly, the medium what crossing into the pipeline must be clean, viscosity less than 4°E.

Front the valve should be installed the 80-100 mesh / filter prevent the valve core be jammed,when the pressure be larger where after the valve, should be install the one-way valve. Prevent the medium backflow or cause the solenoid valve closed lax.

In using should be regular cleaning dirt on the surface of the movable iron core and the piston, in dismouting should check the sealing gasket at the same time, when found damaged should be replaced timely.

This valve is unfavorable use in the explosive dangerous places. If need, please indicate in ordering.

Should be install the by-pass device, to ensure the normal production, for the solenoid valve needs change when failure happens or need cleaning.

According to the range of parameter values on the nameplace, place the down-lead of solenoid valve in the circuit, when installing system, no grounding solenoid valve should be grounded, in order to ensure the safety.

Ordering Instructions:

1. Please indicate the models, specification, supply voltage, medium types, pressure and differential pressure etc when order.

2. Please indicate when order normally open solenoid valve.

2. Any special specifications or requirements, should inquiry when order, negotiable.
