Product Description

YK Series Vacuum Pressure Controller

A specialized low-pressure protection and control solution, the YK Series vacuum pressure controller is engineered to meet the demands of negative-pressure systems. It integrates reliable performance, flexible installation, and robust safety features, making it a trusted choice for precision pressure management in diverse industrial and commercial applications.

Core Features

Wide vacuum pressure range: Supports adjustable values from 15in.Hg (-0.1MPa) to 8PSI (0.05MPa), catering to various negative-pressure protection needs.
Flexible configuration: British pipe thread quick connectors or copper tube welding for installation, plus plug-in/wire connection options. SPST switch with NO/NC contacts offers further adaptability.
Enhanced safety & durability: Fusion-welded stainless steel pressure inductor and full-sealed switch structure prevent leaks and ensure stable operation in harsh conditions. Factory-pre-set parameters eliminate on-site adjustment.

Key Performance Table

Parameter Category	Specification Details
Working Pressure Range	15in.Hg~8PSI (-0.1~0.05MPa)
Burst Pressure	2500PSI
Operating Temperature	Ambient: -30℃～+80℃; Medium: -50℃～+120℃

Working Principle

Built with an internal reversible stainless steel diaphragm. When the diaphragm senses the preset vacuum pressure, it flips to drive electrical contacts to engage or open via a guide rod. As the sensed pressure drops below the recovery value, the diaphragm automatically resets, restoring the contacts to their original state—enabling seamless, automatic pressure control without manual intervention.

Application

Key Application Scenarios

Refrigeration Equipment Low-Pressure Systems

Designed specifically for the low-pressure protection of various refrigeration devices where the protection pressure is negative (below atmospheric pressure). This includes household refrigerators, commercial freezers, industrial refrigeration units, and air conditioning systems. It prevents damage caused by abnormal low pressure, ensuring stable cooling performance and extending equipment lifespan.

Pneumatic, Hydraulic & Lubrication Systems

Suitable for pressure control in pneumatic tools, hydraulic machinery, and lubrication systems across industries like manufacturing, automotive, and engineering. It adapts to ambient temperatures of -30℃～+80℃ and medium temperatures of -50℃～+120℃, reliably monitoring and regulating negative pressure to maintain system efficiency and prevent component wear or failure due to pressure irregularities.
