Description

Brass Main Check Valve for Compressors

Brief Overview

This brass main check valve is the critical component that prevents compressed air from flowing backward into your compressor tank—a fundamental safeguard in any pressurized air system. The T-shaped body with machined brass construction provides the durability required in industrial workshops, manufacturing facilities, and pneumatic distribution networks. For operators managing multiple system components, pairing this valve with a pressure regulation system creates a complete air management solution.

Key Features

  • Check Valve Design: One-way flow architecture prevents tank backpressure from damaging the compressor pump
  • Precision Brass Construction: Machined yellow brass body resists corrosion and maintains seal integrity over extended service life
  • Three Thread Ports: M10x1 relief outlet, 3/4″ pump inlet, and 1/2″ cylinder outlet accommodate standard industrial fittings
  • Service-Accessible Design: Removable hex-head cap on the valve body allows internal inspection and maintenance without full disassembly
  • Hex-Flattened Ports: Wrench-friendly geometry simplifies installation and system troubleshooting
