Flowserve Series 75 Electric Rotary Actuator

Flowserve Series 75 Electric Actuators from Worcester Norbro Actuation Systems add a new dimension of operational dependability and flexibility to modern processes controlled by computers, programmable controllers and other electric control equipment. A multi-function capability permits use of the Worcester Norbro Series 75 actuator throughout the process for on/off, throttling, variable-cycle and any analog or digital control. One of the most reliable electric actuators on the market.

Series 75 actuators can assit in the automating of ball valves and other quarter-turn valves or devices requiring rotary operators. Moreover, their ability to provide power in both directions through selected arcs from 20° through 300° makes them ideal for control of heating, ventilating and air conditioning duct systems and automatic, remotely operated equipment.

Flowserve Worcester C44 Cryogenic Ball Valve

Flowserve Worcester’s experience and expertise in the design of cryogenic ball valves has been recognised throughout the process industry for over 30 years. Utilising a combination of our Fluorofill seat material and our unique 'S' gasket body seal, the valve provides positive shut-off in the most demanding of cryogenic applications. From the original C44 R5 and MC44 designs the seat and body seals have remained a constant feature and with both products now rationalised into the C44 R7, additional technical advantages have been included to provide the best cryogenic ball valve on the market. The Worcester 3-piece ball valve offers a number of technical advantages over other types of valve.

High Flow Rate. The high Cv available from a ball valve compared with a globe valve makes the C44 ideal for loading stations where speed of delivery is critical. The valve is also available as full bore up to DN40 as the C59 series.

Low Body Mass. The one-piece design minimises the mass of the body and therefore makes the valve economic to use. It also provides a weight advantage, making the valve ideal for road tankers and other transportation requirements.

Ease of Operation. The unique low torque seat design and the 90 degree operation of the ball valve makes it ideal for use with both pneumatic and electric actuators with the additional benefit of rotary control if required. When manually operated, the lever provides visual indication of the valve orientation (open or closed) which is critical in the safe loading and unloading of liquid gases.

Ease of Maintenance. The 3-piece concept provides the benefit of easy maintenance through the “slide out” body method.
