Product Description

H41H (H41Y, H61H, H61Y) cast (forged) steel elevated high pressure check valve
Product overview


The product is designed and manufactured in strict accordance with GB/T12235 and API standards. The lift check valve is one of the most important parts in the production process adjustment system. It is the valve that controls the one-way flow of the medium in the pipeline and prevents the backflow of the medium. The valve plate is positioned along the middle for lifting and moving, and the Bush is made of special material with good abrasion resistance and small friction coefficient. The action is innocent and reliable, and the sealing performance is excellent. Products are widely used in petroleum, chemical, pharmaceutical, power industry and other working conditions of the pipeline.
