Overview
The Atkomatic US-500 is a 2-way solenoid valve designed for direct control of fluid media in industrial automation and process systems. Atkomatic has provided over 75 years of reliable, durable solenoid valves, and the US-500 continues this legacy with robust construction suitable for demanding hydraulic, pneumatic, and plumbing applications.
The 3/4″ NPT pipe connection with 1″ port accommodates medium flow requirements in industrial equipment ranging from hydraulic systems to compressed air networks. The 2-way normally closed design provides fail-safe operation when de-energized.
Key Features
- 2-way, normally closed solenoid valve configuration for dependable on/off control
- Handles open & close control of gases, water, oil, steam and other clean media
- 3/4″ NPT pipe size with 1″ port for medium-flow capacity systems
- 3/4″ pipe and 1″ port sizing for drop-in replacement compatibility
- Packless design with no stem packing, tight-closing resilient seats, and minimum moving parts for easy maintenance
- Coil replacement without opening pressure containment and internal parts replaceable without removing valve from system
