一．Product Introduction
Z540H, Z540Y, Z540W type PN16 ~ PN160 steel bevel gear driven wedge gate valve produced by Shanghaiwangye valve Co., Ltd. Bevel gear drive, flange connection, wedge-type elastic gate. The seat sealing surface material is surfacing welding alloy, stainless steel, nominal pressure PN16 ~ PN160. The material of the valve body is carbon steel, chrome molybdenum alloy steel, stainless steel gate valve.The gate valves with gear operation are widely applicable to the fields of petroleum, chemical industry, metallurgy, machinery, power industry, military, water supplying with good reputation and reliability from the users. For purpose of adusting or cutting the flow contains various medium, such as thick granule. Sticky liquid and floating contamination etc.
二.Product Features
The fluid resistance is small, and the sealing surface is less brushed and eroded by the medium.
Opening and closing is more labor-saving.
The flow direction of the medium is not restricted, no disturbance, no pressure reduction.
Simple shape, short structure length, good manufacturing process and wide application range.
