Change-Over Valves / Type 11.7

Product description Three-way change-over-valve with safety gland packing in flange design in accordance with EN 1092-1 and ASME B 16.5 respectively; can be supplied in carbon steel 1.0619 (WCB), stainless steel 1.4408 (CF8M) and low temperature steel 1.6220 (LCC). Use The use of change-over valves allows essential maintenance work to be carried out on a safety valve, without interruption of the plant operation, simply by changing over to the relevant stand by valve, thus protecting the plant against excessiv overpressure. Plants are protected against undue excess pressure by switching over to the relevant standby safety valves. Full blow off capacity is maintained when the change-over-valve switches over from one side to the other. When using change-over-valves in tandem, both hand wheels are linked via a chain wheel in order to assure simultaneous operation. Design features Extremely low resistance coefficients due to optimal flow deflection. On account of this safety valves can be combined to the greatest extent with change-over-valves of the same nominal size Compact weight-saving construction method Reducing pieces (e.g. when mounting on safety valves) can be welded on directly

Compact globe valve

Product description Compact globe valve with fully flushed bellows in straight type, y-type or corner-type; with flanges or buttweld ends and safety gland packing; can be supplied in carbon steel 1.0619 (WCB), stainless steel 1.4408 (CF8M) and special materials. Use For different kind of medium with inflammable, explosive, volatile, toxic or aggressive characteristics, whose delivery must be prevented into the atmosphere. Design in accordance with the Federal Emmission Protection law. Design features Stem with internal roll-formed stem thread and rising hand wheel Multiple wall, fully flushed stainless steel bellows, designed for 10,000 operations Metal back seat Full size safety gland packing made of pure graphite Stainless steel camprofiled bonnet gasket coated by pure graphite, mounted in tongue and grooved bonnet flanges

Non-Return Valves / Type 14.1

Product description Spring loaded non-return-valve in straight type, y-type or corner-type; with flanges or buttweld ends; can be supplied in carbon steel 1.0619 (WCB), stainless steel 1.4408 (CF8M) and special materials. Use Spring loaded non-return-valve to protect system from medium reflow. Design features Metal seat with spring loaded plug; opening pressure approx. 0.2 bar.

Relief Valves / Type 14.3

Product description Spring loaded relief valve in straight type, y-type or corner-type; with flanges or buttweld ends; can be supplied in carbon steel 1.0619 (WCB), stainless steel 1.4408 (CF8M) and special materials. Use Mainly used as bypass valve in small circuits. Operating mode With lockable hand wheel cover and stem lock nut to prevent alteration of the set opening pressure. Changing the opening pressure takes place after removal of the hand wheel cover by turning the hand wheel; by so doing the outer pressure spring is tensioned and adjusted to a defined pressure. The valve is not compensated against backpressure!

Steam Distributers / Type V21.9

Product description Compact steam distributor with integrated bellows sealed globe valves made of 1.0619 (WCB) or 1.0460 (A105) respectively with flanges or buttweld ends. Use Steam heating systems as well as consolidation of condensate pipework. Replacement of conventional manifolds which previously had to be fabricated at great expense of individual components. Operating mode One-piece compact body with 4, 8 or 12 connections positioned sideways of the manifold in order to make it even more compact. The manifolds are produced in modules of 4 connections and can be extended to multiples of 4, by welding the modules next to each other. This whole modular construction can be bolted on site by means of threaded holes situated under the manifolds. Design features Reduced planning expenses due to standard components Simplified procurement of compact units Low weight and small space requirements Costs saving due to lower insulation requirements Safe operation, maintenance-free bellows sealed valves Supplied ready for fitting, tested, mounted and painted
