The need for stainless steel specialty productsEfficient design of clean steam systems and correct component selection prevents:● Expensive product loss● Back-up of condensate, with subsequent product and system contamination● Excessive corrosion and rouging of the steam and process systems● Ineffective condensate removal and control● Reduced process system efficiency● High maintenance costsAll too often, these problems are just accepted simply because no readily available solution exists.

CIP/SIP SystemsMany installed CIP/SIP systems use a manual/automated by-pass system with

relatively low capacity steam traps to control the flow of cleaning fluid and condensate.It can be seen from the above diagrams that there are significant pipework

savings when using a BT6HC instead of the traditional system.The BT6HC can be used on a variety of applications within clean steam and

hygienic systems. Its high cold capacity makes it an excellent choice for joint CIP/SIPsystems and also for drainage of large process vessels where initial condensate

and air volumes are very high but normal running loads are low.

Filtered SteamA filtered steam station produces steam to be

used for direct injection into food products, culinarysteam, or for use in sterilizers and autoclaves.

A complete range of stainless steel traps are available from Spirax Sarco to suit all applications and operating environments.Manufactured in the highest quality corrosion resistant 316L stainless steel materials, Thermostatic and Thermo-Dynamic® trapscan be supplied with a wide range of end connections for use in either tubing or piping systems.

Thermostatic TrapsThermostatic traps are most widely used in process applications,

as they can be designed to be freedraining and operate close to steamtemperature at any given pressure.A large orifice helps eliminate thepossibility of fouling in the presenceof contaminated condensate orcleaning solutions, while minimalcondensate retention and excellentair venting capabilities associatedwith thermostatic traps ensurerapid heat-up and optimumsterilization.

Thermo-Dynamic® TrapsThermo-Dynamic® traps are

more suited to constant pressureapplications, where smallamounts of uncontaminatedcondensate are present, suchas in steam main drainageapplications.

Whatever the application,Spirax Sarco has a wide rangeof trap products available for use inboth Clean Steam and ProcessSystems.

SRV6 User benefits

In order to overcome steam main heat losses,reduce the pipework size, and ensure optimumgeneration efficiency, pressure in a system isnormally higher than that required by individualuser equipment.

To satisfy the requirements of these users,a pressure regulator must be used to reducepressure either within the distribution system,or at each point of use.

The SRV6 Pressure Regulator

The SRV6 is a direct acting regulatordesigned to reduce pressure in clean and puresteam, liquid and gas systems. Available in 1",1-1/2" and 2" sizes, the SRV6 is manufactured in316/316L stainless steel, with all wetted partsmechanically polished to 20 microinches Ra, thenelectropolished. The angle pattern design ensuresthat the valve is self draining, while Tri-Clamp®

compatible connections ease removal and ensurecleanliness. Diaphragm restraints and valve travelstop, which are standard features, preventsexcessive diaphragm movement under vacuumconditions, which extends service life and reducesmaintenance costs.

How the SRV6Pressure Regulator Works

Downstream pressure is set by compressingthe control spring. On start-up, flow passesthrough the main valve resulting in a downstreampressure buildup. As the downstream pressurebegins to rise it acts on the underside of thediaphragm, opposing the spring force and causingthe main valve to move closer to its seat. Thismovement throttles the flow, ensuring that thedownstream pressure is accurately controlled atthe desired set point.

accuracy of control.

S6 & 1808 SS SeparatorSeparators remove moisture fromsteam and gas systems byproviding a drain point for waterdroplets moving along the pipe walland deflecting suspended moistureout of the main flow. The separatortherefore ensures steam/gas isdelivered to its point of use dry —particularly important for equipmentsuch as sterilizers. High efficiencyat wide ranges of flow rates alsominimizes the effects ofcondensate such as erosion,corrosion and wiredrawing ofvalve seats.
