ASCO 8210G094 2/2 Way Normally Closed Pilot Operated Solenoid Valve 1/2 Inch NPT Brass Body NBR Seal High Flow Control Valve For Air Water Inert Gas Industrial Automation Equipment

Product Description:

The ASCO solenoid valve portfolio offers a wide selection of high-performance valves crafted to provide reliable control in various fields such as industrial automation, process control, and hazardous area environments. This extensive range includes multiple series, each specifically engineered to meet distinct application requirements.

Among these, the 551 and 8551 Series consist of pilot-operated spool valves that are perfectly suited for pneumatic control. These valves come equipped with a NAMUR interface and a flexible design that allows a single valve to operate as either a 3/2-way or 5/2-way valve. This adaptability makes them ideal for both single-acting and double-acting actuators, providing a versatile solution for pneumatic systems.

The 8320 and 320 Series includes direct-acting and some pilot-operated 3/2-way valves designed for a broad spectrum of general service applications. Notably, these valves can function without requiring a minimum pressure differential, enhancing their applicability across various operational conditions.

For applications involving liquids, corrosive substances, and air or inert gases, the 8210 and 8262 Series offer pilot-operated 2/2-way general service valves. The 8210 series is recognized for its cost-effective, high-flow capacity, while the 8262 series provides a sturdy 2/2-way valve solution for demanding environments.

The 531 Series features spool valves capable of 3/2 or 5/2 functions and often includes intrinsically safe (IS) options, making them suitable for hazardous locations. Additionally, the 210 Series, including models such as the 8210G094, is tailored for both liquid and gas service applications.

ASCO valves are manufactured using various body materials including black anodized aluminum, brass, and stainless steel (316L). Seal options such as NBR, PUR, and FKM are available to meet different operational needs. The valves come in multiple configurations like 2/2-way, 3/2-way, and 5/2-way, with single or double solenoid designs to support spring return or bistable operations. Many models feature NAMUR mounting interfaces and possess IP65, IP66, or IP67 protection ratings.

For use in challenging and hazardous environments, explosion-proof versions are available, certified according to ATEX, IECEx, UL, and CSA standards. Low-power variants are also offered, ensuring reliable performance while maintaining energy efficiency.

Features:

These spool valves feature a NAMUR interface with threaded port connections, allowing for direct mounting of actuators. Their versatile design supports adaptation between 3/2 normally closed (NC) and 5/2 functions, making them suitable for various operational requirements.

All exhaust ports in this series are pipable, enabling connection to multiple outputs which enhances environmental protection—especially important in clean room settings. Safety is a top priority, with TÜV certification for the 551 series and EXIDA certification for the 551-553 series, meeting safety integrity levels SIL 2 (HFT=0) and SIL 3 (HFT=1).

Additionally, a standard manual operator is provided for straightforward commissioning and ease of maintenance.

The 8320 and 320 series valves are designed for a broad range of general service applications. Their direct-acting mechanism allows operation without the need for a minimum pressure differential, providing flexibility in different system conditions.

Another advantage is their versatile mounting capability, as they can be installed in any position without compromising functionality.

These economical valves offer high flow rates suitable for liquids, corrosive substances, as well as air and inert gases. They are constructed from durable materials, available in either brass or stainless steel bodies, to accommodate various media types.

The 531 series valves provide flexible functionality, configurable as either 3/2-way or 5/2-way valves. They are intrinsically safe and certified for use in hazardous environments where current and voltage must be limited.

Bodies of valves from all series come in multiple materials including aluminum, brass, and stainless steel, offering options that suit different applications and environments. The valves support a variety of voltages such as DC 24V, AC 24V, AC 120V, and AC 220V, ensuring compatibility with diverse power supplies.

For hazardous areas, explosion-proof variants certified by ATEX and IECEx are available, ensuring safety and compliance. Low power versions are also offered, ideal for remote or alternative power locations.

In terms of performance, the 1/4" models generally achieve flow rates of approximately 700 liters per minute, while the larger 1/2" valves can handle up to 3000 liters per minute, catering to high-flow requirements.
