Xiamen Better Silicone Rubber Co., Ltd

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.

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

Silicone Dispensing Check Valve, is also known as Silicone One Way Valve or Silicone Flow Control Valve, is made of high elasticity silicone material. Silicone Rubber Dispensing Valve are designed to regulate the flow of liquids and air, allowing flow at a predetermined pressure in one way and immediately preventing backflow in the opposite direction.

Umbrella Valve also knowns as Umbrella Valve Seals, Umbrella Check Valve, Rubber Umbrella Valve and Liquid Silicone Valves, is mainly made from high-tensile solid silicone (HTV) or liquid silicone rubber (LSR) materials, also made from other rubber materials like Neoprene, EPDM, Fluorosilicone, Nitriles etc. The production of silicone rubber umbrella valves involves a striking balance between efficiency and quality. To achieve this balance, different manufacturing processes must be considered and compared to determine which process better matches the product's particular needs.

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.

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.
