The 4HV series manual valve is a pneumatic control component produced by AIRTAC, mainly used for cylinder direction change and position control. According to different models, their functional characteristics vary, mainly divided into two types: two position four-way valves and three position four-way valves

Basic Structure and Function

All 4HV series manual valves have four interfaces:

P port: air inlet, connected to the air source.

A and B ports: exhaust ports, respectively connected to the upper and lower chambers of the cylinder, control the extension and retraction of the cylinder.

R port: exhaust port, connected to muffler, used to discharge compressed air from the cylinder

Two position four-way valve (such as 4HV310-10)

Function: Control the cylinder to perform reciprocating motion, that is, the cylinder fully extends (to the head) and fully retracts (to the head) to two fixed positions

Application scenario: Suitable for situations where only the cylinder needs to switch between two extreme positions.

Three position four-way valve (such as 4HV330-10)

Function: In addition to controlling the reciprocating motion of the cylinder, it can also achieve the cylinder stopping at any position (middle sealing function), that is, it can stop the cylinder at the middle position of the up and down stroke

Application scenario: Suitable for situations where precise control of cylinder stop position is required, such as positioning, clamping, etc.

Product Features

According to the product introduction, the 4HV series manual valve has the following characteristics

Easy to operate: The direction change and rotation are light, with a good hand feel and accurate positioning.

Flow performance: Large effective flow area and low pressure loss.

Structural design: Adopting an integral slot gap slide valve disc structure, the reaction speed is faster and the operation is lighter.

Processing technology: The valve body is processed using a machining center for higher precision.

Protective performance: Adopting the process of oxidation before painting, the valve body is double protected and can adapt to working in more harsh environments.
