I. Overview

The YZF-J4 pressure control valve is a signaling device that directly converts the pressure difference signal into an electrical signal. It is specially used to control the reversing of the reversing valve. It is installed on the electric terminal type double wire dry oil with a nominal pressure of 10M Pa. Central lubrication system ends of two main oil supply pipes.

II.Technical Parameters

Grease with a penetration of 265 ~ 385 (25 ° C, 150g) 1 / 10mm (NLGI 0 # ~ 2 #)

IV.Model Description

V. working principle

The body and position switch of the pressure operated valve are mounted on a base plate. Under the effect of pressure, dry thin oil grease enters the left (right) cavity of the valve body from the main pipe, and the right (left) cavity is unloaded at this time. Once the pressure difference between the two main pipes reaches 3.5 ～ 4.5MP a, the piston moves to the right (left) against the action of the spring force, closes the contact of the travel switch, and sends a signal to control the solenoid valve to reverse direction, and vice versa Complete a cycle of work.

VI.Instructions for use

1. The pressure control valve should be installed in a place that is ventilated, dry, easy to observe, and has no interference from the movement mechanism.

2. The pressure control valve is installed at the end of the two main oil supply lines.

3. After the pressure control valve, an additional oil feeder must be installed to update the grease in the valve.
