Complete valve control. Inside a single switch.
The PTF-22-PDC connects directly between your power supply and solenoid valve. No controller. No additional hardware. All logic, timing, and hygiene functions live inside the M22 body, programmable via USB, rated at 50 million activations, sealed to IP69K.
No external controller. No extra hardware. Just wire it in.
Standard piezo switches pass a signal to a separate controller, which then drives the valve. The PTF-22-PDC eliminates the controller entirely. The MCU, output driver, firmware, and all programmable logic sit inside the M22 switch body. Wire it between power and valve and it works.
No moving parts, nothing to wear out, seize, or corrode. Solid stainless steel face, IP69K sealed, rated at 50 million activations. Less than 10µA standby enables battery operation for remote installations.
A conventional intelligent shower control requires a piezo switch, a separate controller board, an enclosure, and a wiring harness connecting them. The PTF-22-PDC replaces all of that with one part. The hardware reduction delivers measurable cost savings. Installation is reduced to three connections in a standard 22mm cutout. And the functional upgrade in programmable compliance, adjustable sensitivity, and battery operation comes at no added complexity.
Your installation. Our solution.
Whatever your application requires, voltage, valve type, programming mode, or deployment environment, the PTF-22-PDC adapts. It is not a product built for one scenario; it is a platform built to cover them all.
Runs on mains, battery, or solar. The <10µA standby current makes multi-year battery life realistic for remote or outdoor installations where no mains power is available.
Drives any solenoid valve. Non-latching valves get continuous power while open. Latching valves receive a configurable pulse to open and close; pulse time is adjustable to match any valve manufacturer's specification.
Sensitivity is set in software, not hardware. Set it feather-light for accessibility applications, or firmer to reduce false activations in high-traffic or vibrating environments. Senses through up to 3mm of metal surface.
The PTF-22-PDC is available in every housing format offered in the PT Series range — flat, bevel, recessed, illuminated — in stainless steel or aluminium. Material grade, surface finish, custom graphics, and engravings are all specifiable. M22 and larger formats available. Contact us with your requirements.
Flush solid metal face with no gaps, seams, or mechanical parts for bacteria or moisture to accumulate. IP69K sealed to 100 bar pressure wash. No O-rings to degrade, no moving parts to corrode, no scheduled maintenance required.
Set once. Works forever.
All parameters are configured via the Piezo USB software before installation. Values are stored in non-volatile memory and survive power cycles.
The same switch, programmed for each installation: shower facilities with Legionella-compliant hygiene flush schedules, emergency eyewash stations with weekly activation timers, drinking fountains with flow time and lockout control. Every application, one platform.
Three connections. That's it.
The PTF-22-PDC ships with all three cable sets pre-attached. No crimping, no assembly. Mount in a standard 22mm panel cutout, connect power and valve, program via USB.
