Dual-plate check valves prevent return flow in horizontal and vertical pipelines. They are wafer-type valves of double swing design. For installation in horizontal pipelines, they are fitted with closing springs. For installation in vertical pipes with upward flow, closing springs may be included if required.
Wafer-type non-return (check) valve for sandwiching between flanges. Valve with spring for installation in any position. Without spring only for vertical lines with upward flow. Self-centering valve body ensures accurate installation. Application for liquids, gases and vapours. Please observe the classification according to the Pressure Equipment Directive (PED).
A range of forged carbon steel compact manifolds with integral piston type stop valves for steam distribution and condensate collection duty. MSC manifolds can be used for either steam distribution duty or condensate collection duty depending on the way they are installed.
This equipment is designed for discharging condensed water or air-venting steam lines. Condensate discharge is controlled by the four or nine membrane regulator capsules and the associated nozzle insert. The membrane regulator capsule contains a liquid filling the evaporation temperature of which is a few degrees below the saturation temperature of water (condensate).
Thermostatic steam trap with membrane regulator. Corrosion-resistant thermostatic capsule unaffected by waterhammer. Integral strainer. Asbestos-free cover gasket (graphite/CrNi). Installation in any position. The traps with standard capsule āNā discharge the condensate with virtually no banking-up, the traps with special capsule āUā with an undercooling of approx. 30 K (degC).
GESTRA QuickEM is a pre-assembled drain module to be used in installations for heat recovery. The drain module is suitable for discharging condensed water. The QuickEM assembly consists of two or three shut-off valves, one steam trap type BK..., MK... or UNA..., one sightglass, one wafer-type non-return valve RK... as well as pipes and all necessary flanges, flange gaskets and bolts. Counterflanges with bolts and gaskets are not part of the delivery. The QuickEM Control is designed for electronic condensate monitoring. Instead of the sightglass the measuring electrode NRG 16... is installed as sensor for electronic condensate monitoring.
The GESTRA UNA PK Station and UNA PK HK Station are plug in systems specifically designed to remove condensate from plant under 'stall' conditions. The whole system is capable of handling capacities up to 2 800 kg/h pumping and 9 000 kg/h trapping, depending on available differential pressure.
Water-type non-return (check) valve for sandwiching between flanges. Valve with spring for installation in any position. Without spring only for vertical lines with upward flow. Self-centering valve body. Application for liquids, gases and vapours (observe classification according to PED).

Equipment type CB 14 are wafer-type swing check valves with short overall length to EN 558-1, series 95. The low weight of the equipment is beneficial for transportation, storage and installation. The equipment can be mounted between flanges acc. to the following standards: EN 1092 PN 6/10/16 ASME B 16.1 Class 125 FF and ASME B 16.5 Class 150 RF The equipment can be installed in horizontal or vertical pipes. If the equipment is mounted in a vertical pipe the flow must always be from bottom to top.
