10 Hot Sale Solenoid Valves In COVNA

Solenoid Valve is cheap, simple structure and small size so it plays an important role in various applications. But there are so many types of electromagnetic valves, how do we select them?
In this article, we will share with you the feature and applications of 10 hot sale solenoid valves in COVNA.

2W Solenoid Valve / 2W31 Solenoid Valve / 2W21 Solenoid Valve

These three solenoid valves have a same performance and structure. They are both direct acting diaphragm type and general purpose. Suitable for water, oil, air, gas, etc. Zero-pressure start, can withstand the highest pressure is 10 bar.

The only difference is that they have different coils.

2w: The coil is simple and cheap, but it heats up easily when used for a long time.
2W31: Copper coil, good sealing and dustproof.
2W21: The best of the three, but also the most expensive. The coil is resistant to high voltage and does not heat easily. The body is also harder and has large flow rate. It is durable.

We generally recommend models based on customer usage times, application environment, and budget. For example, if the customer requires good performance, coil is not easy to heat, 1-inch size, budget around $25, we will recommend 2W31.

HK07 Diaphragm Solenoid Valve

The solenoid valve is diaphragm type and requires a pressure of 0.3 bar to start, with a maximum pressure of 16 bar.
So this item can withstand the pressure is the highest in the general-purpose series
Second, the coil voltage power has two options, 24VA 18W and 22VA 17W. Either way, long working time is supported.

HK08 Steam Solenoid Valve / HK10 High-Temperature Solenoid Valve

These two items are pilot piston type, are high temperature solenoid valve.
The difference is that the starting pressure is different.
HK08: 0.3 bar for starting pressure
HK10: 0.5 bar for starting pressure. Its unique structure can help heat dissipation, not easy to burn out the coil.

HKP Waterproof Solenoid Valve

This product uses IP68 waterproof coil, and can operate underwater. Zero pressure start-up. Maximum pressure is 10 bar. Widely used in the fountain industry.

HKFP21 Anti-Corrosion Solenoid Valve

The product adopt PTFE material as the valve body, which means it is suitable for use in corrosive media such as acids and alkalis. Suitable for chemical industry, containing corrosive medium industry.

HKKB High-Pressure Solenoid Valve

The product has a thick seat, which means it can withstand high pressure. The maximum allowable pressure is 250 bar. Suitable for boiler industry and so on.

HK0018 Food Grade Solenoid Valve

The product is made of stainless steel 304 / 316, which means it can pass through the food medium. Such as milk, drink, pure water and so on.
The unique clamp connection mode can effectively avoid the contamination of the medium.
The product is widely used in the food industry.

These are the features and applications of the 10 most popular solenoid valves sold in COVNA.
