Petrolvalves control are specifically design to control flows in severe service applications, both on gas and liquids. The solid design is based on extensive campaign of numerical simulations and experimental tests. 984 Series combines high flow capacity with accurate control at small flow conditions, thus increasing valve rangeability at values once unthinkable for control valves. The side entry split body geometry offers excellent structural strength and versatility of construction, while the trunnion mounted design allows to transfer the pressure load from the trim directly on valve body, to reduce actuating torques and increase lifetime of seals.

The 984 Control Valve incorporates a Multistage Cage Trim inside the ball containing plates with drilled holes, with specific design for noise reduction on gas flows, and cavitation prevention in liquid flows. Trim design allows high control capability, huge rangeability and excellent and long lasting tightness. At low openings, process fluid will go through all drilled plates inside the valve trim. This feature makes possible to handle high pressure drops by controlling low CV values
