Precision Actuation for Industrial Systems

Engineered for accuracy and durability, the Roller Plunger Valve provides repeatability within 0.02 mm and supports up to 120 switching operations per minute. Its compact and robust design allows for base mounting in confined spaces, making it ideal for automation systems, conveyors, and machinery requiring reliable position detection and limit switching.

Robust Build and Extended Service Life

Constructed with a zinc alloy body, stainless steel plunger, and polyacetal roller, the valve boasts a polished, electroplated finish for corrosion resistance. With over 5 million cycles of service life and an IP65 rating, it withstands dust, moisture, and harsh industrial conditions, ensuring long-term, maintenance-free performance.

FAQs of Roller Plunger Valve:

Q: How does the Roller Plunger Valve function within automation systems?

A: This valve is mechanically actuated when a moving part presses the roller plunger, triggering the internal contacts (1 NO + 1 NC) to change state. Its used for position detection, limit switching, and sending signals to pneumatic or hydraulic devices in automation equipment.

Q: What environments are suitable for installing this valve?

A: The valve suits indoor industrial environments requiring IP65 protection, such as automated machinery, conveyors, and factories, operating reliably from -10C to +60C and withstanding dusty or mildly wet conditions.

Q: When should I choose the Roller Plunger Valve with polyacetal roller and zinc alloy body?

A: Select this valve when you require high cycling life, precision repeatability (0.02 mm), and corrosion resistance for automation tasks involving filtered, unlubricated air at pressures from 1.5 to 8 bar.

Q: Where is this valve typically mounted, and what connection sizes are supported?

A: The valve uses a base mounting configuration for stable installation on machinery frames or panels. It supports connection port sizes of either M5 or 1/8 BSP for flexible integration into pneumatic circuits.

Q: What is the process for using or installing this valve in automation equipment?

A: Mount the valve securely using its base mounting holes, connect the selected port (M5 or 1/8 BSP) to your air supply, and wire the contacts into your control system. Position the roller in the motion path where actuation must occur for reliable switching.

Q: Why is this valve beneficial for position detection in automated machinery?

A: It offers rapid response (<20 ms), excellent repeatability, and a long service life, ensuring consistent and accurate detection even in fast-moving industrial processes. The spring return provides automatic reset, supporting high-frequency cycling up to 120/min.
