SANHUA BALL VALVE (GBV series)

Description

Sanhua GBV Series: Features and Details

1. Core Function and Construction

• Function: A manual shut-off valve used to isolate system sections or components.

• Operation: Quarter-turn (90) manual rotation for fast ON/OFF control.

• Design: Straight-way type, full port design (for most common sizes).

  • Benefit: Ensures minimal pressure drop when the valve is fully open, maintaining system efficiency.

• Safety Feature: The valve utilizes a Blow-out Proof Stem design.

  • Benefit: A crucial safety feature for systems using flammable refrigerants like R290, ensuring the stem cannot be ejected under high pressure.

• Leakage: Designed for ultra-low seat leakage and reliable external sealing.

2. Technical Specifications

• Refrigerant Compatibility (Key Feature): Specifically designed and certified for use with Flammable Refrigerants (A3 and A2L), including:

  • R290 (Propane)

  • R32

  • Also compatible with common HFCs/HFOs (R410A, R404A, R452A, etc.).

• Max. Operating Pressure (PS): High-pressure rating, typically 4.5\text{ MPa} (45bar}.

• Medium Temperature (TS): Wide operating range, typically -40C to +120C.

• Connections: Available primarily with ODF (Solder) connections, across common sizes.

• Safety Certification: Often certified to meet European standards (e.g., ATEX) or other regional safety standards relevant to flammable refrigerant applications.

3. Model Variations

• GBV: Standard ball valve with ODF connections.

• GBV with Access Fitting: Includes a Schrader/Service Port on the side.

  • Benefit: Provides a convenient, safe point for service technicians to check pressure or charge the system.
