Installation & Maintenance Instructions

Proper installation and periodic maintenance are crucial for the stable operation, long lifespan, and safety of the MIHA φ60 check valve.

Installation Instructions for DN50 Swing and Spring Brass Check Valves

Step 1: Pre-installation Check

Ensure valve size and thread standard (BS 21 / ISO 228-1:2000) match the pipeline.
Check that threaded surfaces are clean and free of debris or burrs.

Step 2: Determine Flow Direction

Observe the arrow cast on the valve body to ensure correct flow direction for effective operation.

Step 3: Installation

Threaded connection: Use PTFE tape or thread sealant, install the valve in position, and tighten moderately to avoid cracking the valve body.
Recommended installation position: After the pump or before devices needing protection, either vertically or horizontally, depending on system design.

Step 4: Post-installation Check

Test the system, observe the valve’s opening/closing, and check for leaks at connections.

Maintenance Instructions

Maintenance cycle:

Inspect and clean the valve every 3–6 months, depending on operating conditions (clean water, hard water, or with impurities).

Maintenance steps:

Release pressure and drain the fluid from the pipeline before removing the valve.
Remove the valve, clean the disc, seal, and body using clean water or a mild cleaning solution.
Check the seal and spring (for spring valves), and replace if worn, torn, or lost elasticity.

Safety precautions:

Avoid using strong corrosive chemicals or metal brushes to prevent damage to brass surfaces and seals.
Ensure connections are tightened properly during reinstallation.

The MIHA φ60 copper check valve is a reliable solution to improve system efficiency and protection. For convenient maintenance without affecting the entire system, it is recommended to install isolation valves before and after the check valve.
