3 PAROL -9 SERIES ONTROL VALVES The line of PAROL -9 series control valves provides the most versatile globe body type single seat available with heavy top guiding design. They have an unusual combination of premium features that suit them for a wide range of applications, including viscous fluids and slurries, with reduced costs. Due to their simple construction and reduced number of parts, maintenance becomes easier and less expensive. The -9 series control valves can be supplied with a wide range of pneumatic actuators and, on request, electric or electrohydraulic ones for on-off or continuous control duty. Main features and advantages of valves series -9 are listed on the page aside.

4 -9 SERIES ONTROL VALVES FEATURES OF SERIES -9 ONTROL VALVES large free-flow passages with smooth body contour and no dead zones. PAROL ADVANTAGES - higher V values - reduced erosion and contamination - permit handling of slurries and viscous fluids heavy top plung guide only. When the valve is open the plug is out of the seat. - simple and cheaper construction - compact plug design and smooth, contour assures a higher stability - reduced possibility of seizures lower seat diameters. Valves series -9 are provided with the maximum seat diameter above which no increases of valve V are possible. - higher allowable pressure drops - reduced sizes of actuators - better seat tightness when plug is in closed position fewer body and trim parts. The standard trim includes four parts only: plug, seat, stem and p wide range of components and accessories. wide selection of reduced capacity trims for each body size and large material selection. All std PAROL pneumatic actuators are available and in addition electric ones and all possible accessories. - lower maintenance cost - reduced inventory - easier trim substitution - less possibility of damages - higher versatility - wide possibility of applications - safe and reliable services SPEIFIATION BODY Valve type -9 with hydraulic actuator type : globe, single port and non reversible. construction : from casting except for sizes up to and rating above PN 0 which are forged. materials : from stock - ASTM A WB and ASTM A FM. on request - ASTM A LB, r.
