Manifold valve ARCO VA30 1 1/4" MF – straight connection

ARCO VA30 1 1/4" MF – straight connection is a compact manifold valve designed for inline installation in piping systems where controlled distribution and isolation of fluids is required. The valve provides a straight-through flow path with a male-female connection pattern that simplifies assembly in manifolds and pipe runs. It is constructed for industrial use in HVAC, water handling and general process installations where a robust shut-off and flow control component is needed.

Advantages

The straight-body design offers predictable flow characteristics and ease of installation in confined or linear manifold arrangements. A male–female connection eliminates the need for additional adapters in many installations, reducing leak points and saving assembly time. The valve is built for durability and reliable shut-off under typical industrial conditions, and its compact footprint supports use where space is limited.

Suitable for

• HVAC systems for distribution and isolation of heating or chilled water
• Water supply and circulation lines in commercial and industrial buildings
• Manifold assemblies in process plants requiring inline shut-off
• General fluid handling where a straight inline valve with MF connection is required

Key specifications

• Connection type: straight inline with male–female threaded ends
• Nominal connection size: 1 1/4"
• Application: fluid distribution, isolation and shut-off in piping systems
• Typical use environments: HVAC, water handling, industrial fluid systems
• Design form: compact manifold valve suitable for installation in manifolds and pipelines

How to use

Install the valve inline with piping, matching the 1 1/4" male and female threaded ends to corresponding fittings or ports. Ensure threads and sealing surfaces are clean and use appropriate thread sealant or tape compatible with the system fluid and operating temperature. Mount the valve in the intended orientation for straight flow; tighten connections to the recommended torque for the pipe material to avoid overtightening. Operate the valve according to system pressure limits and perform periodic inspections for leaks or wear.

Usage recommendations

Before installation, confirm compatibility of the valve materials with the conveyed fluid and check system pressure and temperature ratings. During commissioning, perform leak tests at operating pressure and include the valve in routine maintenance checks to ensure continued tightness and smooth operation.
