Rotary Control valves

V-Port Ball valves manufacturer (VPB) Maxum™ Rotary Control Valves (RCV)

Major Markets: Paper, chemical, power, petro-chem and gasDesign Features: The V-Port Ball Valve is a quarter-turn v-orifice ball valve for accurate throttling control of fibrous suspension applications plus clean, dirty, viscous and corro- sive liquids and gases. It is designed to meet the highest industry standards for dynamic performance. Flanged or flangeless designs meet ANSI or ISA face-to-face dimensions. Design features include blow-out proof shaft protection, high flow capacity, splined ball-to-shaft connection for ease of maintenance and zero backlash. Industrial seat options include flexible metal, rigid metal and PTFE seats.Size Range: 1–20" (25–500mm) Temperature Range: to 575°F (300°C) ANSI Class Rating: 150, 300 Pressure Rating: to 285–740 psi (1965–5100 kPa) ANSI B16.104 Shutoff Class: Flexible Metal, ANSI Class IV* Reinforced PTFE, ANSI Class VI Rigid Metal, ANSI Class IV *Shutoff is up to 500 times better than ANSI Class IVBody Materials: Carbon steel, 316 and 317 stainless steel, Hastelloy CValve Style: V-port ball, flanged or flangeless Actuator Types: PowerRac® double-acting and spring-return actuators, spring & diaphragm actuator, lever, handwheel, chainwheel Major Markets: Pulp & paper, chemical, power, petroleum, refiningDesign Features: The Maxum™ RCV Rotary Control Valve is an eccentric rotary control valve for throttling liquids, gases and slurries. It combines precise throttling accuracy and control over a full 90° of rotation. Tungsten carbide coated trim components and design features provide superior erosion resistance. The RCV valve is designed for bi-directional flow capability and includes four trim options for flexibility. It is designed for ease of maintenance with no internal threaded components and self-aligning seat and plug. Flanged or flangeless designs meet ANSI or ISA face-to-face dimensions.Size Range: 1–12" (25–300mm) Temperature Range: to 1000°F (540°C) ANSI Class Rating: 150, 300 Pressure Rating: 285–740 psi (1965–5100 kPa) ANSI B16.104 Shutoff Class: Up to 20 times better than ANSI Class IV standardBody Materials: 316 and 317 stainless steel, carbon steel, Hastelloy C, TitaniumTrim Sizes: High, Full, .5 Reduced, .2 Reduced Actuator Types: PowerRac® double-acting and spring-return actuators, spring & industrial diaphragm actuator, handwheel, chain- wheel
