WF Diaphragm Seal Gauge

Diaphragm Seal Gauge with Welded Construction & Flanged Connection

The Budenberg WF is a high integrity Diaphragm Seal Gauge that has been designed to withstand the high pressures and temperatures normally associated with Chemical and Oil / Gas applications. The WF has a diaphragm welded to the Flange.

It's unique feature is the ability to set the diaphragm to ‘lock off’ at set pressures thereby protecting the unit from major overload conditions up to and including 400 Bar. This eliminates the need for expensive overload protection valves.

The WF is available in a wide range of options including a choice of dial sizes, connections, materials, filling fluids and options to permit operation at temperatures in excess of 440°c.

It has been designed for continuous operation on gases or liquids where the pressure element could be become corroded or clogged by the process media. Versions are available to withstand pressure pulsations, vibrations and operation at very high temperatures.

The Budenberg WF specifications

Size	63mm (2.5"), 100mm (4"), 150mm (6")
Accuracy Class	1.0% as defined in EN837
Pressure Range	The welded seal units is available in a range of configurations dependant on the required Dial Size and Operating Pressure range as follows: Dial Size - 63mm / 100mm / 150mm Seal Diameter - 69mm Min Range - 1 Bar Max Range - 400 Bar
Over Range Protection	All units will withstand 130% overload as standard up to 200 Bar. Optionally the diaphragm can be set to 'lock off' allowing the unit to withstand an overload up to the maximum pressure rating of the seal unit. This unique feature can be used to avoid the use and cost of additional overload protection valves.
Materials of Construction	Due to the welded construction, all materials including the diaphragm and connection have to be the same material. Standard - 316L Stainless Steel Other materials available on request.
Process Connections	All standard FR Flanges from 150 to 1500# in sizes 1/2" to 3" All stndard PN10 flanges from DN15 to DN50 Other connections are available
Filling Fluids	A wide range of filling fluids are available to suit most applications including high temperature and pharmaceutical applications. Standard Options - Mineral Oil, Silicon HT Oil, Medicinal Paraffin, Glycerine, Syltherm XLT & 400. Inert Fluorine based fluids can be specified for oxygen and chlorine applications as well as a range of FDA approved fluids for food and pharmaceutical applications.
Temperature	Normal process operating temperature range:  -20 to +100°c Elevated temperature operation up to 450°c can be achieved by the selection of an extended neck option and an associated high temperature filling fluid.
Pulsation Dampener	The clamped design allows Budenberg to offer a snubber internally to dampen pulsations and beneficially protect the Pressure Gauge.
Certification & Traceability	Serial Number Printed on Dial. Certificate of Conformity traceable to National Standards is supplied
Safety	All units are manufactured to comply with EN837-1, S3 Specification and other regulatory standards including PED.

 

Anti Tamper

Designed to prevent disassembly

 

Extended Neck

For use in elevated temperatures up to 300°C we can dissipate the effect of heat from the Pressure Gauge by inserting an extended neck between the WF and the pressure gauge.

 

Remote Mounting

St/steel capillary can be fitted between gauge and seal to protect instrument from heat or vibration

 

Fitting Transmitters

We have a range of standard and 'Smart' Transmitters that can be used in combination with the WF or Budenberg can fit customers own free issue transmitters to most diaphragm seal units

 

Accessories

Valve & Adaptors - a full range of Needle and Ball Valves to fit the WF - See separate Datasheets.
