PTFE Lined Y type Flush Bottom Valve Product introduction

 PTFE Lined Y type Flush Bottom Valve Manufacturer, factory and supplier in China. PTFE Lined Y type Flush Bottom Valve is full PTFE FEP PFA lined, which is mainly used for the bottom discharge of the reflector, storage tank and other containers. Currently, the commonly used fluid-lined ball discharge valve is difficult to meet the special working conditions of strong scouring, easy crystallization and high resistance. 

PTFE Lined Y type Flush Bottom Valve function is mainly for bottom discharge, discharge, sampling and no-dead zone shut-off operations of reactors, tanks and other containers. The bottom flange of the PTFE Lined Y type Flush Bottom Valve is welded to the bottom of the tank and other containers, thus eliminating the residual phenomenon of process media usually at the outlet of the container. According to the needs of the actual situation, the bottom structure is designed for the flat bottom, PTFE Lined Y type Flush Bottom Valve body is V-shaped, and the two working modes of lifting and lowering the valve disc are provided. The inner cavity of the valve body has a scour and corrosion-resistant sealing ring. At the moment of opening the valve, it can protect the valve body from being washed and corroded by the medium, and carry out special treatment on the sealing ring to make the surface hardness reach HRC56-62, which has the function of high wear resistance and corrosion resistance. The valve disc seal is surfacing cemented carbide on the cover when needed. And prevent scarring. At the same time, the design of short stroke valve disc is adopted.

PTFE Lined Y type Flush Bottom Valve Features:
1. Corrosion resistance: It is different from ordinary up-spread and down-spread discharge valves, and can withstand the corrosion of almost all media (including concentrated nitric acid and aqua regia);
2. Good sealing resistance: special cone spool structure is used to open and close the seal;
3. The material has no residue and should not be crystallized: the valve chamber and the tank body are integrated structures;
4. PTFE Lined Y type Flush Bottom Valve Can be equipped with different modes of operation: manual, pneumatic, electric, hydraulic, gear, etc.
5. Easy to operate, open freely, flexible and reliable movement; The spool assembly and maintenance is simple, the sealing structure is reasonable, and the sealing plate replacement is convenient and practical.

PTFE Lined Y type Flush Bottom Valve Working Principle:
1. The upward PTFE Lined Y type Flush Bottom Valve opens the valve upward movement (the spool moves outside the valve body), and the opening is that the valve needs to overcome the medium force, and the opening moment is larger than the closing moment. The upward opening and closing stroke is small, and the installation height is small. Upspread type for use with agitator PTFE Lined Y type Flush Bottom Valve.
Note: The size of the inlet flange is the same as the size specification of the outlet flange or the size specification is different.
2. The downward expansion type PTFE Lined Y type Flush Bottom Valve is the valve disc (plunger) downward movement of the valve to open (the valve core moves inside the valve body), the direction of movement when opened is the same as the medium force, so the opening is smaller than the closing torque. Large opening and closing stroke, high installation height. Underspread discharge to the reactor of the frame anchor agitator.
Note: The inlet flange size can only be larger than the outlet flange size.
