Product Introduction

Rubber Lined Diaphragm Valve is a special form of shut-off valve. Its opening and closing part is a diaphragm made of soft material, and the valve body cavity and bonnet cavity are separated from the driving part. Its iconic feature is that the diaphragm connects the lower valve body cavity with The inner cavity of the upper bonnet is separated. Rubber Lined Diaphragm Valve is mainly used in biopharmaceutical, food, power and other industries

Advantages

● The flow path of Rubber Lined Diaphragm Valve is unobstructed and the flow resistance is small, so that the user can obtain a larger flow rate.

● Its lining materials are diverse, can be applied to various media, and have good corrosion resistance.

● It is not applicable for diaphragm used in medium with hard particles, which will cause diaphragm damage and leakage.

● Its sealing part is a flexible rubber diaphragm, so it has better airtightness and minimal closing force.

● The rubber diaphragm keeps the corrosive medium in the flow channel completely isolated from all driving parts, so as to ensure that the valve stem and other parts are not corroded by the medium.

● Limited by the diaphragm material, the diaphragm valve is suitable for low pressure and relatively low temperature occasions.
