Drain Valve Connection: Size Range 1/4" to 2"

Component Specifications

Definition

The drain valve connection is a critical interface component in industrial trap systems, designed to provide a leak-proof, pressure-resistant connection between the drain valve and the trap body. It ensures proper alignment, sealing integrity, and mechanical stability during fluid discharge operations. This component typically features standardized threading, flanges, or quick-connect mechanisms to facilitate installation, maintenance, and compatibility with various valve types.

Working Principle

The drain valve connection operates by creating a sealed mechanical joint between the drain valve and trap body through threaded engagement, flange bolting, or compression fitting. It maintains system pressure integrity while allowing the drain valve to open/close for controlled fluid release. Proper torque application and gasket/seal compression ensure leak prevention under operational conditions.

Materials

Carbon steel (ASTM A105/A216), stainless steel (304/316), brass (C36000), or engineered plastics (PTFE, PVC) depending on fluid compatibility and pressure requirements. Gaskets: EPDM, Viton, or PTFE for sealing.
