Product Details Introduction

LAV-250-PAA Vacuum Valve Product Description

LAV-250-PAA is a pneumatic controlled vacuum valve, positioned as a vacuum state control and safety protection component in industrial pipeline systems. It has dual operation modes of pneumatic and manual, which can accurately control the on/off of pipelines in vacuum environments. At the same time, it integrates emergency safety cut-off function and is widely applicable to various industrial production scenarios that require vacuum control. The following is a summary of its core information:

1、 Core technical characteristics

-Dual mode operation design: supports pneumatic automatic control and manual emergency operation. In pneumatic mode, when the cylinder is filled with a specified pressure, the piston rises to drive the valve stem to open the valve. After releasing the cylinder gas, the piston, under the action of the spring, drives the valve stem and valve disc downward to achieve closure; Manual mode can directly open the valve by rotating the top handwheel, improving operational flexibility and emergency support capabilities;

-Emergency safety protection: Equipped with a fusible plug safety device, when the ambient temperature around the valve reaches 75 ℃± 5 ℃ (suitable for safety standards in low-temperature tank trucks, storage tanks, and other scenarios), the metal in the fusible plug melts, the cylinder pressure is naturally discharged, and the valve automatically closes, effectively preventing high temperature risks;

-Reliable sealing and adaptability: The sealing structure adopts a sealing element to press the valve seat tightly, which has excellent vacuum sealing performance and can effectively maintain the vacuum degree of the pipeline; It is speculated that the nominal diameter is suitable for the 250mm specification and can meet the vacuum control requirements of medium and large pipelines;

-Industrial grade stable design: using wear-resistant and corrosion-resistant industrial grade components, suitable for complex industrial working conditions; Compact structure, easy installation and maintenance, adaptable to pipeline layout requirements of different installation postures.

2、 Core application areas

-Low temperature energy storage and transportation: suitable for pipeline systems of low-temperature tank trucks and low-temperature storage tank containers, serving as vacuum state control and emergency shutdown components to ensure the safety and stability of low-temperature media (such as liquid nitrogen, liquid oxygen, etc.) storage and transportation processes;

-Vacuum coating industry: pipeline system adapted to vacuum coating equipment, precise control of vacuum on/off and pressure regulation of coating chamber, ensuring the stability of coating process and product quality;

-Food and pharmaceutical processing: used for pipeline vacuum control in food freeze-drying, pharmaceutical vacuum distillation and other processes, in accordance with industrial hygiene standards, can avoid pipeline contamination and affect product purity;

-In the field of chemical engineering and energy, it is suitable for chemical vacuum reactors and energy equipment auxiliary vacuum systems to achieve precise control and safety protection of pipeline vacuum status, and to meet the requirements of complex chemical working conditions.
