LPG handwheel cylinder valve
Details
The LPG handwheel cylinder valve is the component mounted on the cylinder neck that opens and closes the gas flow. VietnhatGas supplies brass-body handwheel valves, either pre-fitted on cylinders made by VietnhatGas or delivered in separate batches to dealers and gas filling stations that need replacement or additional valves.
Construction and materials
The valve is opened and closed by a handwheel, operated directly at the top of the cylinder. The valve body is made of brass, a material commonly used for LPG valves because it allows precise threading and is not corroded by LPG. The product is supplied within the framework of QCVN 04:2013/BCT, the national technical regulation on LPG cylinder safety.
What partners should check when receiving valves
In line with safety requirements for LPG cylinder valves, partners should check:
- Material: withstands the cylinder's working pressure and is not corroded by LPG.
- Tightness: the valve closes tightly with no leakage at the test pressure specified by the regulation.
- Valve protection: a protective cap or guard ring is fitted for transport and storage.
- Marking: a label or engraving showing the manufacturer, serial number, manufacturing standard and inspection date.
Supplied with cylinders or in separate batches
With cylinders: the valve is fitted in the final step of the 7-step cylinder manufacturing process, after the cylinder has passed the pressure test, leak test, powder coating and information stamping. Cylinders leave the factory with a valve protection cap, accompanied by the inspection certificate and the factory inspection sheet for the batch. Learn more at LPG cylinder manufacturing service.
In separate batches: intended for gas filling stations and dealers needing replacement valves during maintenance or cylinder re-inspection. Partners should specify the cylinder type in use (12kg, 45kg or another capacity) and the connector type so VietnhatGas can verify the specifications before delivery.
VietnhatGas cylinders come with a POL or QCC valve option depending on the target market; the connector type of the handwheel valve in each batch is clearly stated in the quotation.
Frequently asked questions
Can the handwheel valve be used on 12kg and 45kg cylinders?
Both the 12kg cylinder and the 45kg cylinder from VietnhatGas are fitted with valves in the final manufacturing step. For cylinders from other manufacturers, the neck thread and connector type must be verified before ordering.
What are the thread specifications and test pressure of the valve?
Thread specifications, test pressure and connector specifications are provided per batch together with the quotation. Please contact us to receive the detailed specification sheet.
Can our own brand be printed or engraved on the valve?
Requests for private branding on the valve or handwheel are discussed per order; mandatory information such as the manufacturer, serial number and standard must still be retained.
