Performance and use of the exhibition type discharge valve: easy to operate, open free, flexible and reliable movement; valve assembly and maintenance is simple, the sealing structure is reasonable, and the sealing ring replacement is convenient and practical. Structure: mainly by the valve body, valve, seal, valve stem, valve gland, bracket, handwheel, flanges, nuts, screws and other parts.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.

On the exhibition type discharge valve, corrosion resistance: 1 using the media such as water, acetone, alcohol, ammonia, barium carbonate, benzene (WCB material temperature using -29 C -425 C). 2 the use of media such as particles, oil, paper pulp, carbon dioxide (stainless steel material can be used temperature -232 C -60 C). 3 prohibited the use of fluoride ionic liquids (such as HF) also cannot use alkali and phosphate (temperature less than 150 DEG C, the concentration of >30%). The general working temperature less than 4 stainless steel and 150 DEG C, the pressure range of 0.6-2.5MPA, more than the prescribed order to explain.

Difference between the upper and the lower:
1 folding and opening and closing stroke
Opening and closing stroke is different, the size of the installation of the size of the exhibition and under the expansion of the release valve open and close a small, small installation height. In the process of opening and closing, the rotating rod is installed in the form of a minimum height, which is to judge the opening and closing of the valve and the position of the valve according to the open and close position indicator.
2 folding opening and closing moment
On the development of the release valve for the valve to open the movement of the valve, open the valve to overcome the media force, open more than the closing moment.
Under development, Zhu Sai type discharge valve for the valve (Zhu Sai) down the movement of the valve open, open when the direction of movement of the media and the same force, and thus open when the closing torque is small.
