Spray Rinse & Steam Handling

Spray Rinse Valve The Fetterolf Spray rinse valve Type 27 SR was developed to wash residue from large tank or reactor walls without having to open or enter a vessel. This feature has two key benefits: safety of personnel for applications with toxic fluids and to reduce cleaning time in batch processes. Spray rinse valves are frequently found in the Plastics & Polymer (especially PVC), Fine Chemicals and Pharmaceutical industries. It ensures a unique two stage efficient spray pattern, while maintaining a simple, rugged design, utilizing the famous SchuF metal-to-metal shut-off, first developed...

Spray Rinse Valve The device efficiently performs the dual functions of: ■ Shut-off and control of the spray water ■ Direction of the spray in a varying pattern to attain complete wash-down of the residue. The valve can also be used to distribute anti-sticking agent. Standard sizes 3/4"up to 2"(DN 50) and ASME 900# positive metal-to-metal shut-off Customised spray pattern, pressure & volume Zero leakage to atmosphere and process-dual Ram seal design Exchangeable seat and spray head No clogging guaranteed, due to pre-designed "leakage" Rotating or linear spray head Electric or pneumatic actuation...

Steam Injection Valves 27SE Steam injection valves are primarily used in the chemical, pharmaceutical and petrochemical in- dustries. They are used to inject steam or any gas into a reactor or vessel. There are two common applications: 1. Direct and quick pre-heating of media and/or vessels 2. Steam stripping and sanitisation to remove monomers or impurities in polymerisation pro- cesses. The choice of a piston or disc injection valve design is process and media driven: ■ A solid piston design is suitable for full bore, high flow rate applications with vibrations. ■ Disc style injection valves...

Steam Injection Valves A piston rising valve, it features a varia- ble number of holes arranged in a stepped linear manner along the piston. A positioner allows you to control the flow of steam into the reactor. The dif- ferent distribution angles of the injec- tion holes ensure an even steam distri- bution throughout reactor, thus ensur- ing maximum thermal efficiency with minimal dilution effect. This valve is also used for the stripping of reaction. Here steam is injected and allowed to bubble up through the batch removing or stripping away the free monomers, as well as residues and im- ■...

Desuperheater Valves Desuperheater (Temperature Control) Valve While superheated steam is often available as an energy source, the use of saturated steam is actually more desirable and efficient. This steam conditioning valve's function is to lower and maintain the steam's tem- perature down to saturation by adding varying amounts of water. Also useable for any other application that involves adding a cold liquid to a hot gas, the valve was developed from the SchuF steam injection valve. Spray nozzles are designed to atomise the liquid to optimise the heat transfer. The quantity of in- jected...

Steam Control & Conditioning Valves These valves reduce and control the pressure and temperature of steam. Steam is generally generated at high temperatures and pressures to ensure high turbine efficiencies. Other steam users in steam heating, heat exchangers use low pressure and temperature steam. A steam conditioning valve produces this steam. A steam control valve is often used as a boiler feed control valve, to control the flow of steam into the boiler. 27DU Steam conditioning valve Features: In contrast to the control valve, for steam conditioning cooling water is injected through the spindle...
