ASCO 34303054 Valve

The ASCO 34303054 is a professional-grade 3/2 manually operated isolation valve specifically engineered for high-demand pneumatic systems and MODULAIR 112 FRL (Filter, Regulator, Lubricator) assemblies. As a padlockable 3-way valve, it provides critical lockout-tagout (LOTO) capabilities, ensuring system safety during maintenance by exhausting downstream pressure when in the closed position. This 1/2" G-port isolation valve features a robust main-operated design that handles high flow rates with minimal pressure drop, making it a reliable choice for industrial HVACR and automation service techs.

Built for durability in harsh environments, the ASCO 34303054 1/2-112 3/2 valve integrates seamlessly into existing Numatics or ASCO Modulair 112 preparation units. Its technical architecture prioritizes ease of installation and operational safety. Whether you are performing a new install or replacing a worn 3/2 main operated valve, this genuine ASCO component ensures precise pneumatic control and long-term performance under rigorous cycling conditions. Focus on maintaining a leak-free seal and proper port orientation for optimal air preparation performance.

Key Benefits

• Enhanced Safety: Integrated padlockable handle supports OSHA-compliant lockout-tagout procedures to prevent accidental pressurization.
• High-Flow Design: 1/2" G-thread ports ensure maximum CFM throughput for downstream pneumatic tools and actuators.
• 3/2 Functional Control: Effectively isolates air supply while simultaneously exhausting downstream pressure in the "off" position.
• Modulair 112 Compatibility: Designed specifically for modular connection to the ASCO Numatics 112 series air preparation line.
• Industrial Construction: Heavy-duty materials resist wear and chemical exposure common in HVACR and manufacturing environments.

Common Questions

Can this valve be used as a standalone unit?
Yes, while designed for Modulair 112 stacks, the 1/2" G-ports allow it to function as a standalone manual isolation valve in any pneumatic line.

What is the primary function of the 3/2 operation in this model?
The 3/2 configuration allows the valve to shut off the inlet flow and vent all downstream pressure to the atmosphere, a critical step for safe technician access.

Does this valve come with the padlock included?
The valve features a built-in lockout hole for safety compliance, but the physical padlock must be provided by the site safety coordinator.
