Umbrella Valve, known as Mushroom Valve, Umbrella Valve Seal or Umbrella Check Valve, which is a kind of one way valve in diaphragm shape for air or liquid pressure relief and backflow controls. It is generally made of high-tensile solid silicone (HTV) or liquid silicone rubber (LSR) materials, also made from other rubber materials like Neoprene rubber, EPDM, Fluorosilicone, FKM, Nitriles rubber etc. It is widely used in many areas for fluid control functions.
Umbrella check valve also known as umbrella valve seal, mushroom valve, which is a non return one way valve and used in air inlet & intake valve for self inflating bag, manual resuscitator, bag valve mask(BVM), manual resuscitation & ventilation bag like Ambu Bag, Laerdal resuscitator. Respirator valve & respiratory umbrella valve is made from medical grade silicone by compression molding or liquird silicone rubber LSR molding.
BVM valve also can be called as resuscitator valve and Ambu Bag valve, which function as non return valve in self inflating manual resuscitator to control oxygen flowing for a breathing or non-breathing patient in an emergency situation. Ambu bag valve includes pop-off valve, pressure limiting valve, non-rebreathing patient valve, PEEP valve, and intake valve, consisting of plastic parts and rubber medical check valve like duckbill valve, umbrella valve, diaphgram disc valve, expiratory valve.
Umbrella Valve Seal, known as Umbrella Check Valve or Mushroom Valve, which is one type of silicone one way check valve ( backflow valve & pressure relief valve). Silicone Umbrella Valve, which have round diaphragm seals & seat for air or water pressure relief and backflow controls like Belleville v
