Z60Y,Z61Y,Z62Y high-temperature and high-pressure welded gate valveDetailed product description：

The main advantages of Z60Y, Z61Y, Z62Y high-temperature and high-pressure welded gate valves are:

(1) Low fluid resistance. The internal medium channel of the gate valve body is straight through, and the flow direction of the medium through the gate valve does not change, so the flow resistance is relatively small.
(2) Opening and closing are relatively effortless. The direction of the gate movement during opening and closing is perpendicular to the direction of the medium flow. Compared to globe valves, gate valves require less effort to open and close.
(3) The direction of medium flow is generally not restricted. The medium can flow in any direction from both sides of the gate valve, achieving the purpose of connection or disconnection. Convenient installation, suitable for pipelines where the flow direction of the medium may change.

Working principle of high-temperature and high-pressure welded gate valve:
Designed and manufactured according to JB/T3395 standards, it can be used in conjunction with domestic equipment. The high-temperature and high-pressure welded gate valve adopts a pressure self tightening sealing structure in the inner chamber, and the higher the inner chamber pressure, the better the sealing performance. The two ends of the branch pipe are welded structures to meet different requirements for connecting pipes. The sealing surfaces of the gate and valve seat are made of Stellite cobalt based hard alloy, which is wear-resistant, high-temperature resistant, corrosion-resistant, and has good abrasion resistance. The valve stem has undergone quenching and surface nitriding treatment, providing excellent corrosion resistance and abrasion resistance. The structure of the opening and closing components can be designed in different forms such as single board, double board, parallel double board, etc. according to user requirements. The welded gate valve is suitable for cutting off or connecting media on pipelines in various working conditions such as petroleum, chemical, and thermal power plants with nominal pressure of 16.0-32.0Mpa and working temperature ≤ 540 ℃ (where P57170V_T working temperature ≤ 570 ℃). Applicable media include: water, oil, steam, acidic media, etc.

The operation modes include manual, gear transmission, electric, etc.
