Dismantling Joint

OV01 SERIES

OV02 SERIES

FEATURES

• Epoxy powder coating
• Ductile iron body
• Stainless steel tie rods
• Fully restrained and unrestrained configurations
• Longitudinal ± 25mm adjustment

OPTIONS

• NBR seal
• Wide selection of fastener materials and finishes:
  Galvanized fasteners
  316 or 304 stainless steel
  Dacromet® coating on fasteners
  Tensile steel 4.8 or 8.8
• Flange drilling connections to suit a wide range of flanging
  standards:
  AS2129 T/ E
  ANSI 150
  EN 1092
• PN25 pressure rating

TYPICAL APPLICATIONS

• The OV01 & OV02 dismantling joints are designed to simplify the installation, maintenance and removal of:
  Isolation valves
  Non-return valves
  Control valves
  Metering & associated equipment
  Pumps & associated equimpent
• The OV01 & OV02 dismantling joints are used in many areas, including:
  Pumping stations
  Water treatment plants
  Sewage treatment plants
  Industrial pipelines
• The OV01's are a traditional dismantling joint, supplied with a complete set of tie rods as 100% restrained, though on request can be supplied as either 25% or 50% restrained.
• The OV02 dismantling joints with fewer tie rods than the OV01 has the advantage of easy and fast installation while still offering a secure and rigid dismantling joint.

DESCRIPTION

OLVO's OV01 and OV02 dismantling joints are double flanged that provides easy installation and disassembly of flanged pipe and associated equipment including valves, meters and pumps. The OV01 and OV02 are widely used for a variety of applications in the water and wastewater sectors, mining and industrial sectors.
The operating principle behind the OV01 and OV02 is that the centre sealing flange is drawn closer to the mating flange, thereby compressing the rubber sealing ring to achieve a complete seal. So simple, yet so effecient and practical.
The OV01 features a single tie rod connecting all three flanges. The OV02 features an end to end tie rod and a seperate tie rod for the sealing flange. It is recommended to check with your local authority too confirm which series is permitted for your application.
