Shavo group of companies has a diversified portfolio with a presence in various industrial engineering sectors.
An h911 series industrial excess flow valve, the poppet is loaded by a spring in a normally open position as long as the system is balanced. If the system becomes unbalanced and the downstream pressure drops, the poppet moves towards the sealing area, and stops prevents free, uncontrolled flow from the line.
If the downstream pressure increases, the ventilation outlet ["bleeding"] enables the system to balance the pressures and with the help of the spring to reset the system. In this situation, the poppet reverts back to normally open.
