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.
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).
