The original German GESTRA Valve B28 ASTM 
 I the German Agency for the GESTRA Products! 

 Germany Gestra, one of the the Flowserve Group's members, the global leader in the design and production of the steam valve and control system is, we can provide customers with a fully intelligent solutions. Many practical applications: positioning control system for steam generation, control, fluid systems, energy saving, environmental protection and safety of our products and services in the following areas. 

 The Gestra-trap and trap testing 

 The GESTRA trap including thermal power, thermal static float three series. Widely used in saturated steam, superheated steam from high pressure to low pressure, from small displacement to the large displacement of a variety of complex industrial conditions. The trap detection equipment online detection performance of the trap, to avoid the loss of live steam. Including TK BK series pilot series UNA float series thermal power type DK, ZK and GK series.

 The GESTRA oils detector / alarm ORGS 11-2 

 Is based on the principle of electrical conductivity measurement. Orgs 11-2 alarms electronic control unit integrated module is one terminal of the housing at a position downstream of the ORGS 11-2 should be added to a control and alarm apparatus, and thus does not require the use of an external switching means, for controlling all the features, to protect the device needs to be cooled, to prevent the leakage may occur. ORGS 11-2 has two channels, to realize fault protection. 
 With a level electrode level limiter for Flanges PN 320 

 The GESTRA-level electrode NRG 111-11 
 Is used to detect the the steam boiler lowest level (low level alarm). The electrode is the electrical conductivity measurement principle, it issued according to the conductivity of the water level signal. 

 Features and advantages of 
 Containing low level limiter for periodic self-test (SMART) function 
 Condition value of the pressure and temperature of superheated steam 
 Can be used for power plant boiler 

 Capacitance level electrode NRG 211 
 Level switch models with GESTRA NRS 2-4 (indicating a high level) and model level switch NRS 2-5 (indicating a low level) used in combination, is applicable to any high-pressure high-temperature conditions (up to PN 320,550% B0C ). Can be installed into the drainage system in the traditional power stations and high-pressure steam boiler. 

 Features and advantages of 

 Without using any moving parts 
 Ceramic tube 
 Maximum pressure of liquid level detection 
 Reliable monitoring turbine drainage system
