Pressure Drop Charts

The curves given in the chart are valid for water at 2 0 ^ { \circ } \complement To read the pressure drop for other fluids the equivalent water volume flowrate must be calculated and used in the graph \dot { \mathsf { V } } _ { \mathsf { W } }

The values indicated in the chart are applicable forspring-assisted valves with horizontal flow and to valves without spring installed in vertical pipes with upward flow.

The self-acting temperature controller consists of avalve featuring a thermostat and a sensor. According to the service conditions the controller is optionally equipped with a cooling unit or a sensor pocket. The temperature sensed by thesensor changes the volume of the measuring liquid in the capillary tube.The resulting pressure acts directly on the actuating piston which, in turn,operates the valve spindle.As the temperature rises,the regulating valve is held in closed positon (heating process) or open position (cooling process) until the pre-set release temperature isreached.

When the temperature drops again,a builtin return spring resets the valve to original position.

Two-way valves,with single seat or pressure-balanced single/double seat. Double-seated, two-way reverse-acting valves or three-way valves for diverting and mixing applications.Valve components made of gunmetal,cast iron, nodular cast iron or cast steel,with flanged or screwed connections.

Thermostat

Valves

The thermostat is firmly attached to the sensorcapillary tube.The rod-,spiral- or airduct-type sensors are made of copper or high-alloy stainless steel.
The capillary tube isavailable indifferent lengths,made of copper or high-alloy stainless steel.

GeSTRA

Safety,reliability,availabilityand economy have always enjoyed toppriority inboileroperation. To an increasing extent,another aspect is being added for the plant operators: process automation and visualization.

To meet these stringent requirements, GESTRA AG has-formore than five decadesnow-been workingexclusivelywithelectrodesystemsthat are low in maintenance and wear; in contrast toothersystems,they functionentirelywithout moving parts,which leads to high service lifetimesand very low failure rates.

By now, these GESTRA electrode systems are beingapplied inmany differentareas of the energysupply centre.Inaddition to the boiler equipment itself, these units are also used in condensate tanks,pump-driven return installations,steamregeneratorsetc.Witha low response sensitivity of > 0 5 \mu { S } / {cm } even operation with demineralization equipment does not pose a problem.In general, the entire energy supply centre isonlyaseffectiveas itsweakest element.Manyplant operators,designersand manufacturersare thereforeno longer prepared to enter into any compromises in this area.

Nothing isas cost-intensive as a production outage.

Over and above these aspects,the requirements for the equipment of an energy supply centre tend to differ greatly.The requirements can no longer be met with one and the same system,aswas perhaps the case only10 to 15 years ago.The wishes expressed by the customers have always been the driving force behind GESTRA's innovative developments,and this is still the case today.

There is no longera “one size fits all" system for customer requirements!

Anotherstepforwardwastakenforthe GESTRA equipment components through the introduction of the SPECTOR family, which focuses on meeting the customer's specific needs.The family now consists of SPECTORcompact, SPECTORconnect, SPECTORmoduleand SPECTORsmart.

SPECTORcompact

SPECTORcompact comprises systems that facilitate the easy replacement of existing self-acting systems.Measurement values are transferredasstandard 4 { * } 2 0 \mathsf { m } A signals or can be incorporated into existing controllers via integrated volt-free relaycontactswithout anyneed foradditional electronic control units. If necessary, controllers are of course also available for implementing the entire controlled systems.

SPECTORconnect

SPECTORconnectofferseasy integrationinto automation concepts by means of remote data transmission and parameter setting.

Thanks to many technical innovations, the design,erection and commissioning of plants is simplified considerably.A tried and tested system that meets the requirements made on boiler equipment today and in the future. Now, with SPECTORconnect,a large amount of process-relevant data can be transmited for the first time.Further information is given in the separate brochure “Equipment for Energy Supply Centres-SPECTORconnect"

SPECTORmodule

The SPECTORmodule line represents a systematic advancement of the proven GESTRA technology. Using the most modern electronic components and constituting the state of the art, thesesystemswere designedwitha focus onease of handling,reducing the installation expense,and providing cost-effective solutions.

New units were developed as demand-oriented solutionsforboilerautomation.Thescopeof the parameterization was limited to the most essential functions to ensure intuitive operating of the controllers.

Dependingon the task at hand,the customer canchoose between the systemvariants SPECTORmoduleandSPECTORmoduleTouch.

SPECTORmodule concentrates on the key functions,and the parameters are set by means of a rotary pushbutton.

SPECTORmoduleTouch

The SPECTORmodule Touch version focuses on the essentials:the main functionsand a clear, intuitive user interface.

With this series, the controller was separated from the operating unit,which means that the laborious wiring for sensors,feedback,limits, valve actuation etc in the control cabinet door is no longer required.

Universal controllers generally entaila large number of parameter settings,making the operating workflowand the setting of parameters more difficult.

In the development of the SPECTORmodule Touch series, clearand easily understandable operatingwasatoppriority.

Thanks to the intuitive user interface, the operator can enter the parameters rapidly and reliably.The colour touch display leads directly tothe parameterization level.A virtual numerical keypad is shown,so that values can be changed or functions selected.

Carewas takentoensure thatthevarious controllersalways have thesameclear, uniform operating structure.

To give customers and plant operators greater convenience,we design our systems with a focus on

optimized system interfaces minimized maintenance
