MV Series Pneumatic Mechanical Valves

Features & Key Specifications

Features & Key Specifications of Our MV Series:

Extensive Range of Actuator Types:
We offer a comprehensive selection of operators to suit any application, including the popular roller lever (R), direct-acting plunger (Blank), and various push button styles (flat, round, locking EB).

Versatile 3/2 and 5/2 Way Functions:
This series includes 3/2 way models for sending simple "on/off" pneumatic signals, and 5/2 way models that can directly control the extend and retract strokes of a small double-acting cylinder.

Ideal for Position Sensing:
Engineered to be a dependable pneumatic limit switch, these valves provide a clear pneumatic signal when a cylinder reaches the end of its stroke, a door is closed, or a part is in position.

Compact & Durable Design:
With small body sizes and common 1/8" and 1/4" port options, these valves can be installed in tight spaces. The robust aluminum alloy construction ensures a long service life in a -20°C to 70°C temperature range.

Global Thread Compatibility:
To meet worldwide requirements, we offer three standard thread types: NPT for North America, BSPP (G), and BSPT (P).

Application Fields

Common Applications for Mechanical Valves:

Pneumatic Limit Switch: The primary application, used to detect the end-of-stroke for a pneumatic cylinder.

Position Sensing: Confirming the presence or position of a part in a fixture.

Mechanical Logic Circuits: Creating simple, non-electrical "AND" or "OR" logic controls.

Safety Confirmation: Ensuring a safety guard is closed before a machine can operate.

Manual Signal Input: Using a panel-mounted push button valve for an operator to initiate a cycle.

Technical & Selection Guide

How to Choose the Right Actuator

Roller Lever (R): The most versatile option. Ideal for actuation by a moving cam or a cylinder's striker, as the roller smoothly absorbs side-load.

Plunger (Blank): For precise, direct, in-line actuation. The small pin requires accurate alignment.

Push Button (PP, PB, PPL): For manual activation by an operator. Ideal for control panels.

Locking Button (EB): A push button that stays down when pressed and pops up when pressed again. For maintained on/off manual control.

FAQ

Frequently Asked Questions

Q: What is a pneumatic limit switch valve used for?
A: It's used to send an air signal when it is physically touched by a moving part. Its most common use is to detect when a pneumatic cylinder has fully extended or retracted.

Q: What is the difference between a mechanical valve and a solenoid valve?
A: A mechanical valve is actuated by physical force (a push, a roller). A solenoid valve is actuated by an electric signal. Mechanical valves are used for sensing and simple logic, while solenoid valves are used for automated control from a PLC.

Q: What is the difference between the 3/2 way and 5/2 way versions?
A: A 3/2 way valve acts like a simple switch, sending a single "ON" signal when pressed. A 5/2 way valve acts like a crossover switch, directly controlling a double-acting cylinder's movement.
