ASCO 320-S Series 8320 Series General Purpose solenoid valve

ASCO 320-S Series:

Introduction: General purpose solenoid valve designed for a wide range of applications.

Features: Direct acting valve suitable for wide voltage range, harsh environments, direct mounting, trickle flow control and long life structure.

Applications: Analytical and diagnostic equipment, dust collector systems, life sciences, newsrooms and metal stamping.

ASCO 320-S Series (8320 Series) is a direct-acting general-purpose solenoid valve designed for harsh industrial environments. It supports a variety of media control (such as air, inert gas, water, light oil), and has explosion-proof, low power consumption, long life and other characteristics. The following is a detailed introduction and model list:

Core Features

Structural Design

Direct-acting operation, no minimum pressure difference is required to work, and the response is fast (usually < 50ms).

Compact design, the valve body material can be brass or stainless steel, suitable for corrosive environments.

Functional Features

Wide voltage compatibility: supports AC/DC multi-voltage specifications (such as 12V DC, 24V DC/AC, 110V AC, 230V AC), and some models support a wide voltage range (such as 24 - 240V AC/DC).

Explosion-proof certification: Optional explosion-proof coils (such as ATEX, IECEx, UL Class I, Div 2) are available for hazardous areas.

Long life design: By optimizing the sealing structure and materials (such as metal-metal seals), a cycle life of up to 20 million times is achieved, which is suitable for high-frequency action scenarios.

Application scenarios

Industrial automation (such as cylinder control, fluid distribution).

Dust removal systems, medical equipment, packaging machinery, food and beverage industry.

Harsh environments (such as humidity, dust, high temperature) or occasions requiring explosion-proof certification.

Common models

The following are some typical models of ASCO 320-S series (including key parameters such as voltage, interface size, function, etc.):

Selection Tips

Voltage selection: Select the matching model according to the on-site power supply type (AC/DC) and voltage value (such as 24V, 110V, 230V).

Interface size: Common 1/8", 1/4" NPT or BSPP threads, which must be compatible with the pipeline system.

Function type:

Normally closed (NC): Closed when de-energized, open when energized.

Normally open (NO): Open when de-energized, closed when energized.

Universal (U): Can be configured as NC or NO.

Explosion-proof requirements: For hazardous environments, select models with ATEX, IECEx and other certifications (such as EF or IS prefixes).

Media compatibility: Stainless steel valve bodies are suitable for corrosive media (such as water, chemical liquids), and brass valve bodies are suitable for air and inert gases
