 Germany Gestra is one of the members of Flowserve Group, the steam valve and control system design and production is a global leader, we can provide customers with a fully intelligent solutions. Our products and services in the following areas have many practical applications: steam generation, control, fluid systems, energy saving, environmental protection and safe position control system. Test the Gestra-trap and trap. 
 The GESTRA the trap including thermal power, thermal static and float three series. Widely used in the superheated steam to saturated steam from high pressure to low pressure differential displacement, from small to large displacement of a variety of complex industrial conditions. Trap detection equipment can detect the performance of the trap, to prevent live steam loss. Including the BK Series TK pilot series UNA float series of thermal power type DK, ZK and GK series, etc.. Bi-metal trap-BK series features: from the role of water hammer and frost, built-in check valve for superheated steam within the applications made of stainless steel can be installed in any position typical model: BK212 BK28, B28, ASTM, BK29, BK45, BK35, BK45, the hydrophobicity of the diaphragm-of MK series of ultra-sensitive response features built-in check valve internal stainless steel can be installed in any location Typical Model: MK45-1 MK45-2, MK35/31, MK45 A-1 MK36/51 and UNA float series - is not the environmental impact of back pressure and condensing water temperature does not appear to the accumulation of condensate in the state of extreme load and pressure fluctuations. Typical model: UNA13 UNA15, UNA23 UNA25, UNA26, UNA27, UNA39 and other applicable special occasion trap-AK45, UBK46, SMK22, MK20, TK23, TK24GESTRA - check valve, gravity circulation check valve-the SBO-return pressure valve-RK70, RK71, MB14 for public health and HVAC for heating and hot water systems, steam and gas environment can be used as the destruction of the valve flange on the folder DISCO non-return valve (for industrial and HVAC systems) -RK41, RK44, RK76 apply to liquids, gases, steam RK41 is particularly suitable for the RK44 for sea water and drinking water treatment the RK76 applicable in industrial environments, non-return valve-RK86 (suitable for industrial applications) patented design 1) comply with a number of international standards in the heating system 2) easy to install stainless steel material to apply to the corrosive medium and low temperature valve (special applications)-RK16A, the RK49 stainless steel RK16A series: 1) apply to the corrosive media 2) a minimum temperature of -200 ° C RK49 series: 1) suitable for high-pressure environment 2) maximum temperature to +550 ℃ check valve-CB, WB, the NAF short design to save space suitable for a variety of media environment suitable for the different closing spring GESTRA-safety valve, filter valve filter the GSF, SZ safety valve globe valve GAV The GSV ball valve GESTRA oil detector / alarm ORGS 11-2 is based on conductivity measurement principle. The electronic control unit of the ORGS 11-2 alarm integration module of a terminal shell, used to control all functions, thus eliminating the need to use an external switching device to a control and alarm devices should be added downstream of the ORGS 11-2 protection needs of the cooling device to prevent possible leakage. ORGS 11-2 has two channels, the real fault protection. With one level electrode level limiter for Flanges PN 320GESTRA-level electrode NRG 111-11 for the lowest level (low level alarm) in the detection of steam boilers. The electrode is based on conductivity measurement principle, it is issued under the conductivity of the water level signal.
