The Hemispherical Valve Seal also known as an inflatable dome valve seal or a plug seal. Hemispherical valves are preferable for managing chemically forceful or high-temperature materials. They are widely used on pneumatic conveying systems or in applications ranging as the content can be increased by bagging and issuing food products into vessels. This is a full bore method inlet/outlet opening valve with a hemispherical dome element that opens and closes. The heavy-duty and wear-resistant Inlet valve now has the longest component life. This claim is supported by our customers. We start manufacturing Hemispherical Control Valves that can handle amazingly abrasive materials and operate at high nonlinear loads.
