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. |

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. |

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.
