Product Description

Reactor/Container/Boiler/Tank's Bottom Discharge Valve(ZPL100 Series),PTFE-lined baiting valve,emptying valve

Products Overview.
The bottom discharge valve is primarily use for discharging materials from the bottom of reactors, tanks, and other containers. This valve is connected to the bottom flange, effectively eliminating any residual medium typically found at the container outlet. As a specialized cutting valve predominantly employed in various storage containers' bottom. Its sleek streamlined design of the valve body flow channel and spherical single seat valve core type facilitate smooth medium flow. Widely applied in polymerization reactions, chemical fiber production, food processing, fermentation processes, and other industries; it also proves to be an ideal choice for slurry material and high-density fluid applications. When selecting valves from this series, it is crucial to consider factors such as temperature, pressure levels, adhesion properties, corrosiveness of the medium within the storage container to optimize performance under different operating conditions.

Variety & feature of bottom discharge valve:
*Fluoroplastic-lined down-open discharge valve: ZPL170F (corrosion-resistance ,Anti-impede)
*Metal down-open discharge valve: ZPL170Y (Anti-impede)
*Fluoroplastic-lined up-open discharge valve: ZPL180F (corrosion- resistance, Anti-impede, Anti-scouring,anti-  crystallization,Anti-blocking)
*Metal up-open discharge valve: ZPL180Y (Anti-impede, Anti-scouring,anti-crystallization,Anti-blocking)
*Fluoroplastic-lined horizontal discharge ball valve: ZPR740F (corrosion-resistance ,Anti-impede)
*Fluoroplastic-lined diagonal discharge ball valve: ZPR741F (corrosion-resistance ,Anti-impede; suitable for installation at the bottom of an inverted U-shaped reactor)
*Metal horizontal discharge ball valve: ZPR780F (Anti-impede)
*Metal diagonal discharge ball valve (Anti-impede; suitable for installation at the bottom of an inverted U-shaped reactor)


1. ZPL170 down-open Discharge Valve features a valve disc that operates within the valve body, requiring it to overcome the force of the medium when closed. The closing force surpasses the opening force, making this valve suitable for reactors with non-crystallizing media.
2. ZPL180 up-open Discharge Valve is designed with a valve disc that moves outside the valve body and towards into the inner of reactor. When opened, it needs to counteract the force exerted by the medium. The opening force exceeds the closing force, making this up-open valve use for reactors equipped with stirrers and prone to crystallization.


The features:
1. Our bottom discharge valve is compatible with various media, and for corrosive substances, can use fluoroplastic-lined valve to meet the requirements of strong corrosion applications.
2. A bottom guide is employed to prevent material stack and crystallization, while also reducing the run-length of the valve core to prevent deformation of the valve shaft.
3. The discharge gate and container are positioned at a 45-degree angle with a curved transition,can makes facilitating smoother material discharge. Additionally, it effectively increases the distance between the container bottom and discharge gate, resolving installation issues related to concave outlet ends.
4.Utilized a multi-spring aluminum air-cylinder,to reduce size and weight of cylinder at the bottom of the container,.By adjusting wire range and spring length, output force can be increased or decreased to meet different product specifications requirements.
5. The air-cylinder allows for single-acting or double-acting functions by adding or removing springs respectively. Furthermore, changing spring installation direction enables positive or negative actions for up-open or down-open bottom discharge valve.
6. An external PT100 explosion-proof temperature sensor can be added for online temperature monitoring as well as 4-20mA remote monitoring in control room to regulate material temperature within containers.effectively solving the safety concerns during material reactions.
7.The valve can be equipped with limit switches for remote position display purposes.The equal percentage curve processing on its valve core combined with a positioner can achieve the regulation function.
8.Adding a Corrugated pipe structure provides dual protection against hazardous corrosive media.
