How to Choose the Appropriate Model

Criteria	Selection Recommendation
Supply pipe size	DN50: choose FHIA-0050 or FHBA-0050
Required material	Standard environment: select ductile iron body (FHIA) – Humid or corrosive environment: select brass body (FHBA)
System pressure	PN10 or PN16, depending on the existing water supply system
Aesthetic requirements	Red epoxy coating to match fire hose cabinet/box
Hose connection compatibility	Select a type with a lug adaptor compatible with the existing fire hose

Note: It is recommended to refer to the fire protection system drawings or consult a technician before purchasing to ensure full compatibility.

Technical Installation Guide for Fire-Fighting Angle Valves

Step 1: Preparation before installation

Check the valve for dents, cracks, or missing accessories.
Ensure the water supply pipe is clean and free of debris.
Verify that the threaded connection is compatible with the supply pipe.

Step 2: Installation procedure

Screw the angle valve onto the pipe in the correct threading direction, using PTFE tape to ensure a tight seal.
Tighten by hand or with appropriate tools, avoiding over-tightening to prevent thread damage.
Attach the fire hose reel to the adaptor lug, ensuring proper alignment and a secure fit.

Step 3: Inspection and commissioning

Turn on the water to check for leaks at joints and the valve disc.
Operate the handwheel to ensure smooth valve operation.
Close the fire hose cabinet and label it clearly.

Technical Tips:

Do not install the valve at a low position prone to flooding.
It is recommended to install the valve at approximately 1.0–1.2 meters above the ground for easy operation.
Conduct regular inspections and maintenance every 6–12 months.
