GESTRA is the global leader in the design and production of valves and control systems for heat and process fluid control. Being a member of the Flowserve group, we are capable of offering our customers complete and intelligent solutions engineered to function with maximum reliability.

Our products and services have many practical applications and are employed where:

  • steam is generated, distributed or used

  • fluids flow

  • energy saving is possible

  • environmental protection and safety-oriented control systems are needed.

  • To be able to operate a plant over along period with an optimum efficiency, the choice of the correct valves is of vital importance. Amongst these valves are steam traps which have an important role to play. Steam must be trapped within heating equipment until it has surrendered all heat energy, at which point the condensate thereby formed must be immediately discharged. The optimum efficiency of a steam-heated plant is dependent upon the performance of steam traps. One type of steam trap cannot be equally well suited for the various applications and requirements, therefore GESTRA offers a comprehensive steam trap range developed and refined on practical applications over the years. The choice of the steam trap type depends, of course, on the plant condition. We are willingly prepared to assist you in selecting the most economic solution for your particular application.

    BK Thermostatic Steam Traps

    Duo Stainless Steel (Bimetallic) Regulator PN 40 - PN 630

    Features of the BK series:  Robust regulator,  Unaffected by waterhammer and frost,  Suitable for superheated steam applications, Stainless steel internals, Installation in any position

    MK Thermostatic Steam Traps

    Membrane Regulator PN 25 - PN 40

    Features of the MK series:  Very sensitive response characteristic,  Function is not impaired by high back pressure,  Built-in non-return valve,  Stainless steel internals,  Installation in any position,  High hot-water capacities

    UNA Ball-Float Traps

    Features of the UNA series:  Unaffected by back pressure and condensate temperature,  No loss of live steam,  No banking-up of condensate even with extreme load and pressure fluctuations,  Particularly well suited for heat exchangers,  Unaffected by dirt,  Automatic thermostatic air-venting,  Repairable in-line,  Ideal for discharging cold condensates & distillates & condensates derived from chemical products

    UNA 25-PK Pump Trap

    The pump trap UNA 25-PK is a modern valve which combines the function of a float trap with an additional pump mechanism. With the UNA 25-PK, you have a product that always drains your plant reliably. No matter whether a heat exchanger tends to bank up condensate in the partial or low-load range or whether an unfavorable pipe layout repeatedly leads to an accumulation of condensate in riser pipes, with the UNA 25-PK you can protect your installation and prevent thermal waterhammer.

    Control Valves

    Temperature Control Valves

    GESTRA temperature control valves ensure optimum utilization of cooling water and hot water of thermal oil. For cooling applications the cooling-water control valves (GESTRAMAT®) type CW are available, for hot-water or thermal-oil heating systems the return-temperature control valves (Calorimat) type BW are used. In many cases these self-acting valves produce the same result as far more expensive temperature control systems.

    For many years now, GESTRA control valves of the type ZK have given proof of their reliability under extreme operating conditions. Long experience and know-how form the sound basis for a generation of eff cient and tight-closing control valves for applications in power stations. Thanks to the easy maintenance and repair of the valves as well as the extremely high wear resistance afforded by the design, reliable operation is achieved together with a long service life.
