1 General Specifications Bulletin No. MCE-B 07E Model 8A-BS & 8A-BSH SEAL-RING BALANCE TYPE CAGE GUIDED CONTROL VALVE Model 8A-BS and 8A-BSH Cage Guided Control Valve realized very limited seat leakage like single seat valves with installing small actuator like double seat valves. This design adopted Seal-Ring Balance on Cage for Type BS and same design on Valve Plug for Type BSH. Seal-Ring inserted in Cage for Type BS and inserted in Valve Plug for Type BSH, seals the guide clearance tightly between Valve Plug and Cage to prevent the valve inlet pressure comes into the Bonnet. This design makes the outlet pressure comes into the upper and lower side of the Plug and it makes the pressure well balanced. Consequently, small actuator is required to operate the valve.

2 2. FEATURES Model CV V Port Type Model CV is cage guided control valve and is used for most general purpose with V port of cage characterized, proving wide applicability, excellent characteristics at high load, and easy maintenance. Typical Application General services Chemical For medium or high pressure Type CQ for quick opening is also available. 8A - BS 8A - BSH Model CS Multi-hole Type Model CS-BSH helps to attenuate aerodynamic noise in gas service, with Multihole in outer cage. In liquid service which may occur cavitation, CS helps to prevent trim from cavitation damage. Typical Application Low noise valve Anti-cavitation valve Anti-erosion valve Model CS-L Double Stage Multi-hole Throttling Type Model CS-L is double stage, multi-hole throttling type control valve providing fixed orifice at the bottom of cage of the Model CS. Because of double throttling mechanism, these valves permit large noise reduction effect. Typical Application For medium and high pressure gas Steam control valve Low noise valve

Please install the valve in correct direction. Wrong installation will increase seat leakage and shorten Seal Ring life cycle. This valve is not applicable to a system reverse pressure is expected. Various Option is available on request. ANSI/FCI class V seat leakage ratio is available as option. Seal Ring design for seat leakage class V is deferent from class IV. Please select single seat valve or pilot balance type valve when severe seat leakage ratio less than 0.01% is required on type 8-BSH. 7Application service is limited as follows because of Seal Ring material property for Type BS and BSH control valves. Type BS It is not acceptable to use Type BS for following application. Food processing service Oxygen service Any process, coloring by resin is undesirable. Acids at high temperature and pressureaqua Regina, Nitric Acid, Sulfuric Acid, Hydrochloric Acid, etc. Fluorine gasf2, CIF, OF2 etc. at high temperature. Metal-hydrogen compound such as % KOH, B2H etc. Type BSH It is recommended to use Type BS BSH control valves within the following range because of Seal Ring material properties to prevent oxidation. For Air service 0 00 For steam and Non-oxide service 0 8It is applicable to use type 8-BS valves for some services listed on7above, by changing the Seal Ring materials. Please contact our sales office for special application. 9It is not recommended to install type 8-BS and 8-BSH horizontally. It will decline the sealing performance. Type 8-BS seal ring design is not recommended for the services required frequent operation or exposed rapid temperature change to protect the life cycle or sealing performance of the seal ring. It is recommended to change Seal Ring on every overhaul services like Gland Packing or Gaskets. Kindly keep some Seal Rings for your stock.
