Control Valves

1. Price Type A Type S N_Moore N /16 Features Tuchenhagen Flow Components, LLC Special Products – Control Valves Control Valves Tuchenhagen currently offer four valve types to provide flow / pressure modulating capability. • Type A • Type S • Type N with Moore Positioner (N_M) • Type N with 2 Position Stop (N/16)

2. Tuchenhagen Flow Components, LLC Special Products – Control Valves Type A See Catalog Sec 3.1 • 316 stainless throughout, including actuator housing • Actuator can be reversed to change from normally closed to normally open positions. • Easily increase product pressure resistance by adding springs to actuator or increasing actuator size – up to 360 psi (OD 1 & OD 2). • Each valve size comes with a number of Cv values in equal percentage or linear trim and soft seat options. • Non-Standard Cones Made to Order • Cv can be easily altered by replacing seat and plug of different value. • Three stage seat to prevent cavitation in high pressure drop applications. • Divert or converge options available for mixing and blending • Pneumatic and Electro Pneumatic Positioners • Hart Module, Profibus, Ex options

3. Tuchenhagen Flow Components, LLC Special Products – Control Valves Type S See Catalog Sec 3.1 • 316 stainless wetted parts with plastic coated steel actuator. • Actuator can be reversed to change from normally closed to normally open positions. • Product pressures to 150 psi.g • Each valve size comes with a number of Cv values in equal percentage or linear trim. and soft seat options. • Cv can be easily altered by replacing seat and plug of different value. • Pneumatic and Electro Pneumatic Positioners

4. Tuchenhagen Flow Components, LLC Special Products – Control Valves Type N_Moore See Catalog Sec 1/8 & XXX Standard VARIVENT® shut off valve Type N fitted with control cone and Moore Positioner Fitted with a pneumatic Moore positioner mounted to a Delrin base, this valve provides an economic alternative to the Type A or Type S Control Valves. Easy to calibrate and in normally open or closed positions, standard VARIVENT actuators can be utilized for product pressures up to 116 psi.g.

5. Tuchenhagen Flow Components, LLC Special Products – Control Valves Type N/16 See Catalog Sec 1/8 & 2.2/2 Standard VARIVENT® shut off valve Type N fitted with control cone and 2 position stop. Besides closed and fully open, the valve can be pneumatically driven to two partially open positions. Fully adjustable, the limit stops are mechanical providing precise and repeatable positioning. Proximity switches can be fitted to the lantern Typically used for coarse and fine flow adjustment for dosing applications

6. Tuchenhagen Flow Components, LLC Special Products – Control Valves Standard Kv Values See Catalog Sec 1/8 & 2.2/2

7. Tuchenhagen Flow Components, LLC Special Products – Control Valves Divert / Converge DIVERT Flow diverted into two ports from one. CONVERGE Flow converges from two ports into one.

8. Tuchenhagen Flow Components, LLC Special Products – Control Valves Actuators • Type A • Max product pressures different for normally open or normally closed valves. • MPP can be increased by adding springs from 3 to 6. • From OD 2.1/2” valve up, MPP can also be increased by selecting larger (MFIII-30) actuator. • Type S • Max product pressures different for normally open or normally closed valves. • Type N/16 and N_Moore • Select Max Product Pressure from standard actuator charts. • Note that 2 position stop type change with change in actuator

9. Tuchenhagen Flow Components, LLC Special Products – Control Valves Accessories ELASTOMER SEALS Available all valve types EXCEPT Divert / Converge valves and 3 Stage Seat Valves. With Seal Metal / Metal 3 STAGE SEATS For high Delta P applications, the pressure is dropped across 3 orifices. Note that Kv values are lower than for standard cones (designated S in manual)
