GCV Three-Port Control Valves QLM and QLD Series
The QLM and QLD are three-port control valves which have linear characteristics for mixing or diverting service. These valves can be used on thermal oil, compressed air, steam, condensate and some other fluids.They are available in four body materials: cast iron, SG iron, carbon steel or stainless steel. All valves can be supplied with the standard metal-to-metal seats, stellite facing for increased resistance to wear or soft seats for tight shut-off.

Steam Traps STERIline® SMK 22-81, SMK 22-82 Suitable for clamp connections to DIN 32676, for pipes to DIN 11866 (DIN 11850, ISO 1127, ASME-BPE) PN 10
The thermostatic steam trap features minimum stagnant area and a corrosion-resistant membrane regulator unaffected by waterhammer. Used for discharging condensate and air-venting steam in sterile and aseptic applications. The membrane regulator with rolling ball features a selfcentering valve cone that can move freely, thereby ensuring steam-tight shut-off unaffected by dirt particles. High response sensitivity thanks to small dimensions of the regulator (evaporation thermostat). Automatic air-venting and discharge of condensate without any banking-up within the whole pressure / temperature range. The opening temperature is approximately 5 K below the boiling point.

Steam Traps Kondensomat® MK 36-51, MK 36-52 Stainless Steel Design, DN 1/4", 3/8", 1/2", 3/4"
Thermostatic steam trap with integral strainer and corrosion-resistant membrane regulator (thermostatic capsule) unaffected by waterhammer. The standard version “N” of the thermostatic capsule discharges the condensate with virtually no banking-up, the version “U” with approx. 30 K undercooling.

Self-Monitoring Level Electrode NRG 16-11, NRG 17-11, NRG 19-11
NRG 1...-11 level electrodes operate on the conductivity measurement principle to detect when the fill level has dropped to minimum (water shortage) in a steam boiler. The NRG 1...-11 combines with an NRS 1-50 level switch acting as a water-level limiter (equipment with safety function). For use in steam and hot-water plants in accordance with EN 12952 and EN 12953.

High-Level Alarm Level Switch NRS 1-51
The level switch NRS 1-51 is used in conjunction with level electrodes NRG 1...-.. as high level alarm in steam boilers and (pressurized) hot-water plants. A high level alarm prevents the water level from exceeding the preset max. water level (HW) and for this purpose switches off e. g. the feedwater supply.

Visual display and operating unit URB 60
The URB 60 visual display and operating unit collects the data telegrams in the CAN bus from GESTRA sensors and control units using the CANopen protocol. When the system is started, the connected devices are automatically recognised by the URB 60 and entered in a list of equipment along with all parameters. The groups, their home screens and navigation buttons are displayed dynamically.

Non-Return Valve SRK 22A
The non-return valve SRK 22A ensures unidirectional flow in pipes by preventing a backflow of fluids. The valve disc is pressed against the seating surface in the event of reverse flow. As a result, the closed valve prevents a backflow of fluid. The guide ribs ensure correct alignment of the valve disc. When fitted with springs, the equipment can be installed in any plane. Different types of springs with different strengths are available. The force of the spring ensures that the valve only opens when the fluid flows in the right flow direction.

Level switch NRS 1-50 for two electrodes
The level switch NRS 1-50 is used in conjunction with level electrodes NRG 1...-.. to limit the water level in steam boilers and (pressurised) hot-water plants. Water level limiters switch off the heating when the water level falls below the set minimum level (low water).
