V9S3 Brass LPG Cylinder Valve
The V9S3 is a manually operated LPG cylinder valve supplied for South African-market applications. Its valve body and handwheel are both made of brass, giving it an all-metal construction for repeated handling in cylinder filling, storage and distribution.
Compared with models using aluminum handwheels, the V9S3 offers a full-brass operating assembly. It is intended for customers whose cylinder and regulator systems require the specified inlet and outlet connections, pressure parameters and valve configuration.

As a gas cylinder control valve, the V9S3 opens and closes the LPG passage between the cylinder and the connected equipment. Its integrated relief device has a specified setting of 2580 kPa. This is the relief setting, not the normal pressure delivered to an appliance; a compatible regulator is required for downstream use.
The 3/4-14 NGT male inlet and G5/8-LH female outlet should be checked against the cylinder neck and regulator connections in the intended system. Confirming these interfaces before ordering helps ensure the valve matches the customer's equipment and installation requirements.

Customization and Market-Specific Supply
Shanghai Luzhen can supply the V9S3 in its standard configuration and discuss customization for different cylinder designs or purchasing requirements. Depending on the project, options may include alternative connections, body markings, branding, packaging and other agreed technical details.
Customers can share their specifications, drawings or physical samples for evaluation. If a particular national standard, certification or document is required, it should be identified during the inquiry so that its applicability to the selected configuration can be reviewed before order confirmation.
The V9S3 is intended specifically for LPG service. Valve selection should always be based on the gas medium, working conditions, connections and requirements of the complete cylinder system. Contact Shanghai Luzhen with your required specifications and quantity to discuss supply for South African-market LPG cylinders.
