Ball Valve Fittings

WA 125 Retractable Fitting

After retraction of the immersion tube, the sensor can be serviced, cleaned, or replaced during the running process. The outer electrode is replaceable. A temperature detector is integrated in the sensor for exact temperature compensation.

SensoGate Retractable Fittings

Universal, pneumatically operated retractable fitting in a modular design for fully automatic operation.

Compact, dirt-proof fitting for very simple installation, providing particular ease of maintenance and high availability.

High Availability
The sensor lock-gate principle allows rinsing the O-rings during the stroke movement. Therefore, the integrated O-rings are notably less exposed to stress than in conventional fittings. Wear is reduced and durability is increased.

Safety
The point of separation between the stroke cylinder and the calibrating chamber is double sealed and ventilated. This prevents the entry of media from the calibration chamber into the drive, and also in reverse the entry of compressed air into the calibration chamber. SensoLock prevents the immersion in the process when the sensor has been removed.

Plug & Play Installation
The central multiplug contains tubings for rinsing, cleaning, and calibration media, including limit switches and check valves and enables a fast, safe, and space-saving connection.

Easy Maintenance
The particular ease of maintenance of the sensor lock-gate is achieved by a well thought-out design that allows performing virtually all maintenance on the site without the aid of a workshop. The drive and immersion tube can simply be separated by loosening a coupling nut, without complete dismantling. The immersion tube is divided by a bayonet coupling to allow replacing only the particularly stressed process-wetted part including the calibration chamber, which helps to reduce costs.

Modular Design
Thanks to its unique modular design, SensoGate provides all common process connections and enables easy replacement of the process-wetted parts by the customer. Various process-resistant materials (PVDF, PEEK, 1.4435, 1.4571, and Hastelloy) are available. You can also simply change from gel-electrolyte to liquid-electrolyte (pressurizable) sensors.

Effective Rinsing and Superior Immersion Depth
SensoGate enables a deeper immersion of the sensor compared to conventional designs. A further feature is the use of short (225 mm) standard sensors for all immersion depths. This removes the need for expensive and fragile glass electrodes in 425 mm lengths.

Ceramat Retractable Fittings

WA 150/WA 153
Pneumatic sensor lock-gate with application-specific process adaptation. Available in carbon-fiber-reinforced PVDF and PEEK (WA 150), stainless steel, titanium and Hastelloy (WA 153).

Applications:
The WA 150/153 is particularly suitable for highly corrosive processes (chlorine production, phosgenation) and for processes with depositing, abrasive and incrusting solids. Other fields of application are flue gas desulfurization, gas scrubbers, sugar production, dyes and pigment synthesis, special incrusting industrial wastewaters.

WA 160
The unique sensor lock-gate with ceramic sealing to the process, immersion version.

Unique lock-gate principle
The usual O-ring seal problems occurring in conventional retractable fittings are eliminated. The O-rings are replaced by two highly planar, polished ceramic disks which separate the calibration chamber from the process by a rotary movement. The ceramic seal between the calibration chamber and process is harder than steel and extremely resistant to chemical, thermal and mechanical influences - a guarantor for highest availability and process safety. The Ceramat sensor lock-gate has proved particularly successful in extremely difficult processes where standard O-ring seals fail. The process-wetted outer housing (PVDF, PEEK, or steel) always remains static and is therefore not subjected to mechanical stress. The unit is driven by a compact pneumatic rotary-lift motor with positively controlled, integrated valves.

Maintenance without process interruption
The particular ease of maintenance of the sensor lock-gate is achieved by a well thought-out design that allows performing the few maintenance operations required on the site without the aid of a workshop. A unique feature here is the simple separation of the complete drive unit under full process conditions. I.e. the process medium, which is potentially corrosive, hot, poisonous, and under pressure, is reliably sealed off. This also allows cleaning the calibration chamber under process conditions when the sensor is broken.
