TESCOM 20-1100 Series regulator is designed with lightweight aluminum construction for onboard compressed natural gas (CNG) vehicles 7 liter engines and larger. This regulator offers higher flow capacity than the 20-1000 Series and accessory options such as solenoid valve and pressure sensors.
Main Application
  • Compressed natural gas vehicles 
Application Details 
The CNG pressure regulator system was specifically developed for the engine injection system of CNG vehicles. The main function is the reduction of the tank pressure to a preset outlet pressure. The system contains a pressure regulator with filter and heat exchanger, a solenoid shut-off valve (high pressure), a pressure relief valve and up to two optional pressure sensors (high pressure and/or low pressure). The pressure regulator is based on the TESCOM 20-1000 Series CNG regulator which has been used in this market for more than 10 years. The pressure regulator is a single-stage, spring loaded pressure regulator with a balanced main valve. The regulator is piston sensed providing enhanced safety and long service life. It’s simple to install with screws included.
