Male Threaded Butterfly Handle Brass Gas Valve Gas Valve Gas Ball Valve Customized

Specification

What is Gas Ball Valve?

A gas valve is a mechanical device installed in gas pipelines to control the flow, pressure, or direction of flammable gases (like natural gas, propane/LPG, or manufactured gas). 

Design Drawing

Feature

1.Ultra-Low Pressure Design

Nominal Pressure: 0.022 MPa (22 kPa / 3.2 psi) – Optimized for low-pressure gas/fluid systems.

2.Multi-Medium Compatibility

Suitable for: Natural gas, Manufactured gas, LPG (Liquefied Petroleum Gas), and Water.

3.Robust Temperature Tolerance

Operating Range: -10°C to 80°C – Reliable performance in varied climates.

4.Standardized Threading

Thread Standard: ISO 228 (G-series) – Ensures global compatibility and leak-proof sealing.

5.Compact Butterfly Valve Structure

Flange Dimensions:

Bolt Hole Centres: 65.5 mm

Flange Diameter: Φ40 mm

Bolt Hole Diameter: Φ31 mm – Compact design for space-constrained installations.

Applications

1.Residential Gas Systems:

Low-pressure branch lines for cooktops, water heaters, or space heaters using natural gas/LPG.

2.Specialized Gas Distribution:

Manifolds for biogas, laboratory gas lines, or low-pressure industrial gas circuits.

3.Water/Low-Pressure Fluid Control:

Cooling systems, irrigation, or low-head water supply networks.

Usage Precautions

1.Pressure Limit Compliance

NEVER exceed 0.022 MPa – Risk of valve failure/leakage. Verify system pressure matches this rating.

2.Medium Compatibility Check

Confirm fluid/gas type aligns with specifications (e.g., no corrosive/flammable liquids beyond water/LPG).

3.Temperature Constraints

Avoid environments below -10°C (risk of seal brittleness) or above 80°C (degradation risk).

4.Thread Integrity

Use ISO 228-compliant fittings only. Apply thread sealant (gas-rated for gas applications; PTFE for water).

5.Installation Orientation

Install with flow direction aligned with valve arrow (if marked). Avoid inverted/pressure-reverse mounting.

6.Leak Testing Mandatory

Pressure-test with soap solution or gas detector post-installation. Never use open flames.

7.Exclusion for High-Pressure Systems

Prohibited for:

Standard LPG cylinder valves (>0.8 MPa),

Natural gas mains (>5 kPa),

Compressed air systems (>1 bar).

Safety and Compliance Instructions for Selecting Gas Valves

• Certification: Ensure valve carries regional safety marks (e.g., CE, AGA, or GB for target markets).
• Professional Installation: Gas systems require licensed technicians – DIY is illegal and hazardous.
• Material Warning: Verify body/seal materials (e.g., brass/EPDM) resist specific media (e.g., sulfur in man-made gas).
