2 Steam Taps Non-Retun-Valves BK Range Steam taps with egulato of DUO stainless steel up to PN 630. BK taps ae suited to the toughest opeating conditions. The DUO stainless steel egulato makes this steam tap paticulaly esistant to watehamme and fost. BK 45 In applications up to PN 40. Fo ai-venting. Type SBO Gavity ciculation checks ae used to pevent gavity ciculation in heating and hot-wate installations. Depending on the type, they ae fitted by union nut to the ciculation pump o with a theaded connection at the pump outlet. The SBO types ae available fom DN 3/4 to DN 1 1/4. MK Range Steam taps with membane egulato up to PN 40. The GESTRA themostatic capsule exhibits vey high contol pecision in dischaging the con densate. This ange is suitable fo both small and lage condensate fl owates. MK 45 2 Fo lage con densate flowates, up to 22 ba. Fo ai-venting. Type RK 41 Made of special bass (DN ) o gey cast ion (DN ) and with metal-to-metal seating, the nonetun valve RK 41 is suitable fo liquids, gases and vapous, and fo use in heating installations. Soft seats available, PN 6 16, DN , shot oveall length to DIN EN 558-1, seies 49. UNA Range Steam taps with ball fl oat up to PN 160. Especially suitable fo condensate dischage without banking-up, fo exteme and sudden fl uctuations of pessue and condensate fl owate, Tap Monitoing The Vaposcope VK makes the fl ow pocesses in pipelines visible by sight-glass. Fo moni to ing the heat exchange sufaces and con den sate piping. The Vaposcope can be used in hoizontal o vetical pipewok without any modifi cation. UNA 1 (left) and UNA 2 Adaptable fo hoizontal o veti cal installation. Type VK Type RK 86 This non-etun valve distinguishes itself fo standad ap pli cations in piping systems as well as fo use with coosive media and low tempeatues. Soft seats available, PN 10 40, DN , shot oveall length to DIN EN 558-1, seies 49. Type CB The swing check valve CB 26 is a cost-efficient unit fo applications involving liquids, gases and vapous. This ange can be supplied in extemely shot oveall lengths fo DN and PN 40. Type BB The dual-plate check valves BB, DN , shot oveall length to DIN EN 558-1, seies 16, ae chaacteized by low pessue losses and high eliability. Also suitable fo gaseous media. Special vesions ae available with plate dampes and vaious linings. 2

3 Poduct Oveview Continuous and Intemittent Blowdown Valves SBO 21 Type MPA Fo automatic, pogam-contolled intemittent blowdown of steam boiles and waste-heat boiles. Especially suited fo boiles opeating without constant supevision (TRD 604). DN 20 50, PN MPA 46 RK 41 Type BAE Continuous blowdown valves with adjustable stage nozzle, sampling valve and electic actuato fo automatically contolled continuous blowdown. Especially suited fo boiles opeating without continuous supevision (TRD 604). DN 15 40, PN RK 86 BAE 46 BB CB 26 Cooling Wate Contol Valves Type CW Opeating without auxiliay enegy, the cooling wate con-tol valves type CW, PN 16, DN , ae popotional contolles which egulate the cooling wate flowate of the uses o plant components individually as a function of the cooling-wate etun tempeatue.

4 Tempeatue/Pessue Contol Valves Backgound: Enegy Recovey Type 5801 Diectly contolled pessue-educing valve with lage set-point anges fo steam, gases and liquids. Type Cloius Self-acting tempeatue contol valves of the type Cloius opeate as nomal- and evese-acting valves with extenal feele. Suitable fo applications with steam, gas and liquids. Contol Valves Fo the automatic contol of the level, tempeatue, pessue and flow of liquids in heat engineeing and pocess-contol technology. DN , PN 16/40. With pneumatic o electic actuatos. Enegy Recovey afte Continuous Blowdown Afte continuous blowdown, iespective of whethe automatically contolled o manually set, it is easily possible to utilize the dissipated heat. Fo example, in a GESTRA blowdown flash vessel, the enegy geneated by the continuous blowdown in the boile blowdown is ecupeated to a lage degee by flashing. In a esidual blowdown coole located downsteam, the heat emaining in the flash vessel can also be used to peheat the feedwate. Ou expeienced specialists in industial systems engineeing ae available to you fo individual advice. In Gemany, the heat ecovey plants made by GESTRA ae eligible fo an investment subsidy; accoding to the Income Tax Law and the Investment Subsidy Law, the gant amounts to 7.5 %. Spae Pat Kits By using genuine GESTRA spae pats, you can be sue that you equipment will continue to function pefectly, that no poblems will occu duing installation and that the ight mateials have been selected with egad to the equied pessue and tempeatue stability. Natually, the GESTRA waanty also applies to the spae pats to the full extent and all statutoy povisions ae met. 4
