The entire diaphragm seal system is completely welded and coated with acid-detecting paint providing a visual alert in the event of a process leak around the diaphragm seal. All Welded System Eliminating Potential Leak Points and Assuring Tamper-Proof Installation Gold Plated Monel Diaphragm Available for Aerated HF Service Acid Detecting Paint on Seal Body Assembly Cleaned per ASME B40.1 Level IV and Shipped in Sealed Bag

Reotemp’s Model PLS Plastic Chemical Seals provide complete isolation of pressure measurement instruments such as dial pressure gauges, pressure transmitters, and switches from a wide variety of corrosive or ultra pure process fluids. Also know as a Gauge Guard or a Gauge Isolator, the Model PLS features all non-metallic wetted components, offering a robust, durable, and economical solution to pressure measurement applications in Wasterwater, Water Treatment, Chemical Processing, Deslination, and other applications where plastic piping is traditionally used.

Reotemp’s Threaded Offline Welded Diaphragm Seals are designed with an upper and lower housing bolted together with a diaphragm welded to the upper housing. This removable design allows for easy cleanout of the seal chamber, while still maintaining the system fill. The threaded offline diaphragm seal can be adapted to fit almost any pressure instrument and process application. Welded Diaphragm for Maximum Durability Wide Variety of Diaphragm and Material Options Continuous-duty Disc Protects from Process Fluid Leaking in the Event of a System Breach Easy Cleanout of Diaphragm Cavity without Compromising Filled System

Reotemp’s Threaded Offline Non-Metallic Diaphragm Seals are designed with an upper and lower housing bolted together with a Teflon or Viton diaphragm bonded to the upper housing. This design allows for the lower housing to be removed for easy cleanout of the seal chamber while still maintaining the system fill. The Teflon and Viton diaphragms are ideal for protecting the pressure instrument from corrosive process fluid. Removable Lower Housing Design for Easy Cleanout Wide Variety of Plastic and Metallic Lower Housing Materials Highly Sensitive and Corrosion Resistant Diaphragm High Displacement Diaphragms Ideal for Mechanical Differential Pressure Gauges and Low Pressure Gauges

Reotemp’s Flanged Offline Welded Diaphragm Seals are designed with an upper and lower housing, bolted together with a diaphragm welded to the upper housing. This removable design allows for easy cleanout of the seal chamber, while maintaining the system fill. The flanged offline diaphragm seal can be adapted to fit almost any pressure instrument and process application.

Reotemp’s W9FR two-piece flanged flush-face seal keeps the process stream sweeping clean across the diaphragm to prevent solids buildup. Its insert-style, all-welded construction lets the diaphragm and sealing face be fabricated from an alloy other than the flange—ideal when Tantalum, Hastelloy, Monel, or other exotic wetted materials are required. The rotating flange further simplifies bolt alignment during installation. Multi-piece Seal Design Bolts Directly to Process Flange Center Instrument Exit Commonly Supplied with Flush/Calibration Ring Ideal for Gauge or Differential Pressure Transmitters

Reotemp’s W9FF flanged flush-face seal is a one-piece, all-welded assembly. The diaphragm is integral with the flange, giving a crevice-free surface that keeps process flow sweeping across to prevent solids buildup. It is the most economical choice for 316 SS service, and can also be supplied in solid Hastelloy, Monel, Alloy 20, and other exotic alloys when enhanced corrosion resistance is required. One-piece Seal Design Bolts Directly to Process Flange Center or Side Instrument Exit Commonly Supplied with Flush/Calibration Ring Ideal for Gauge or Differential Pressure Transmitters

The Extended Diaphragm Seal is ideal for highly viscous and dry powder applications. Its unique design eliminates dead space in piping. It is often used for flush mounting in thick-walled vessels and is available in standard and custom lengths.
