LPG Multivalves

We offer a wide range of multivalves designed for use in car LPG and CNG tank installations.

A multivalve is a crucial component of a pressure tank, mounted directly on the gas cylinder. It combines multiple valves in one housing, including a check valve, 80% fill-stop valve, solenoid valve, manual working valve, excess flow valve, pressure safety valve, and thermal fuse. These valves are essential for ensuring the proper and safe operation of an LPG tank. The multivalve also controls gas flow from the tank to the system and measures the gas level, displayed on the car’s dashboard switch.

Types of LPG Multivalves Multivalves are available in different designs tailored to specific tank types: cylindrical and toroidal.

Cylindrical Multivalves

Cylindrical multivalves are commonly used in cylindrical tanks for automotive LPG systems. They ensure safe and efficient refueling while controlling LPG flow into the system. Equipped with essential valves like a check valve, thermal fuse, and solenoid working valve, these multivalves guarantee reliable operation of the tank.

Toroidal Multivalves

Toroidal multivalves are used in toroidal tanks, which are popular for their compact design. These valves include features like an 80% fill-stop valve to prevent overfilling, an excess flow valve to protect against uncontrolled gas leaks, and a pressure safety valve to prevent overpressure in the tank. Additionally, toroidal multivalves come with a level indicator for monitoring gas quantities.

LPG and CNG Multivalves

Our catalog includes a wide selection of toroidal and cylindrical multivalves, along with spare parts.

Differences Between LPG and CNG Multivalves

LPG and CNG multivalves differ in design and purpose. LPG multivalves are engineered for automotive LPG systems and include components like check valves and solenoid working valves for safe and efficient operation. In contrast, CNG multivalves feature an 80% fill-stop valve and excess flow valve, vital for safe CNG use. These differences stem from the distinct properties of LPG and CNG, necessitating unique technical solutions.
