DVC TYPE 6000 INSTALLATION OPERATION AND MAINTENANCE MANUAL TYPE 6000 DESCRIPTION LOM 6000 TEMPLATE UK 050213 1 PAGE 1 INSTALLATION OPERATION AND MAINTENANCE MANUAL 1 General Precautions a Material Selection The possibility of material deterioration in service and the need for periodic inspections is depended on the contained fluid Carbide phase conversion to graphite oxidation of ferrite materials decrease in ductility of carbon steels at low temperature even in applications above 29 C are among those items For information about corrosion the user is requested to take attention or consideration to determine the suitability of material in their application b Pressure Temperature rating The Pressure Temperature rating is considered for static pressure Please refer to P amp T rating section on page 4 for working precaution The allowable temperature is between 20 C and 160 C do not exceed the temperature range to avoid danger accident happen c Fire safe condition Generally the application of the valve shall comply with the Pressure Temperature rating range If the risk of fire is major effect user is recommended to select our fire safe products which with API 607 approval Contact to the valve distributor or manufacturer for details d Liquids with high fluid velocity When valves must be operated frequently on liquids with very high velocity a check shall be made with the valve distr
3. ibutor or manufacturer for appropriate advice to minimize the possibility of seat deformation especially when they are highly pressurized on high temperature line e Throttling service Valves are generally not recommended for throttling service where both the fluid flow and the solid particles can damage or deform the resilient seats causing leakage High fluid velocity or the presence of solid particles in suspension will further reduce seat life in throttling applications f Do not disassembly when bearing pressure Valve is not equipped with pressure access device User should check it by other method through its piping system g Do not touch the valve surface on high temperature h Not allowed for unstable fluid otherwise specified with catogory Ill in Declaration of conformity or and in this user manual LOM 6000 TEMPLATE UK 050213 1 INSTALLATION OPERATION AND MAINTENANCE MANUAL KA DVC TYPE 6000 2 Product Description 2 1 3 PC SPRING LOADED CHECK VALVE a Valve in which the obturator movement is linear and in the seating area at right angle to the direction of flow b The 3 PC SPRING LOADED CHECK VALVE are used to check and control liquid media e g sewage and wastewater where the media has solid matter volume of more than 5 a free flow is required for operational safety reason 2 2 Product specification This operation manual cover the scope of product specifications are as following Category Ca
