5. Production Control 2. Characteristics of Product UNIFLO’s Control valves are designed and manufactured for durability, long life cycle and maintenance ease as follows: - Double Free Operation : Heavy top-guiding ensures stable and optimized operation of the UNIFLO Products throughout the entire stroking range. The effects of unexpected system upsets or heavy vibration are minimized with this construction. - Reduced Noise Levels : The optional multi-hole low noise trim designs provide single-stage and double stage noise attenuation benefits. Potential noise reduction levels of up to 25dBA are possible, depending on the specific operating conditions. - Long Life-Cycle

: Optional Anti-cavitation trim is also available in single stage and double-stage configurations. Proper control of dynamic cavitation conditions is extremely important for continuous high performance and operation of control valves.

- Lower Cost

: Dependable tight shutoff of a control valve minimizes loss of process fluids, and can potentially eliminate the need for separate isolation valves. The optional soft seat design, provides bubble-tight shutoff capabilities in accordance with ANSI/FCI and IEC requirements.

13/64

5. Production Control UNIFLO’s Shut-off valves are engineered & tested for long life service under million cycle. - Lower torque : There is no frictional contact between Stem / Disc / Ball and Soft / Metal Seat, which makes frictional almost close to zero, thus markedly reducing operation torque. The upper and lower journal shaft bearing provide high compression strength and low friction. So those UNIFLO Valve operations are very smooth and easy.

- Long life service : When the Stem/Disc/Ball contact the tapered face of the Soft/Metal Seat, a complete seal is attained, which results in long life service.

3. Special Process UNIFLO is special processing control with welding work on the metal Body & Parts of the product as follows. - When found to any external defects, Casting shall be repaired by welding. - When repair welding done after the casting has been heat treated, or when heat treatment is required by the specification, the casting shall be re-heat treated. - Whenever a defect is removed, the excavated areas shall be examined by Non- Destructive Testing (NDT), such as Radiographic Test (R/T), Dye Penetrate testing (P/T), Magnetic Particle Testing (M/T) and Ultrasonic Testing (U/T). - All welding processes are in accordance with ASME VIII and IX are covered by relevant qualifications - UNIFLO’s welding engineers can choose from a variety of carbon and stainless steel to apply to critical item areas for the improves performance and extends valves life.

Excellent long-term accuracy and reliability is achieved through the use of multiple springs in the actuator. The rugged one-piece yoke, the pressed steel diaphragm case and the special nylon reinforced diaphragm provide dependable, high thrust performance. Additionally, the precision formed diaphragm eliminates friction and reduces variations in the effective area during operation which, in turn, results in exceptional linearity. Five different sizes of the UNIFLO actuators an optional top or side-mounted manual override is available on both direct and reverse actin with various accessories can virtually satisfy all application requirements.
