Flush Bottom Type Ball Valves

Flush Bottom Type Ball Valve image

Flush bottom ball valves are used for discharging of processed materials from the bottom portion or at the outlet of vessels, tanks, reactors, containers etc. In these Flush Bottom Valves, the valve size are designated by two values. First value stands for the inlet flange connection size, which is fixed to the tank or vessel bottom pad. Second value stands for the size of the port and the outlet flange size which is connected to the pipe. In all the sizes the inlet are always larger in size than the outlet.

Features of Flush Bottom Ball Valves

  • Better flow capacity for line size.
  • Suitable for drainage system.
  • Tight closing for reliable shut-off even after change in pressure & temperature is sudden and extreme.
  • Wide selection of actuator to meet stringent process requirement.
  • Flexible design capabilities allows fitting in any vessel configuration.
  • Measurement temperature is available with built-in thermometer.
  • Jacketed option available (Full jacketed & Semi jacketed)
  • Unique packing designs to suit various temperature & fluid needs.
  • Excellent shut-off performance.
  • Valve Size : NPS 1” to 8” ( DN 25 to DN 200 )
  • Pressure Rating : ANSI 150#, 300# & 600# Equivalent to BS 10, DIN, IS, JIS etc.
  • Body Material : Carbon Steel, Stainless Steel, Duplex, Super Duplex, Monel, Inconel, Hastelloy, Aluminum, Bronze and Higher Alloys available on request.
  • Plug Options : Contoured
  • Flow Characteristics : ON – OFF
  • End Connection : Flanged (RF, TG)
  • Leakage Class : Class IV & V ( Metal to metal seated ) & Class VI ( Soft seated ) as per FCI 70-2
  • Temperature Range : -73 to 500°C
  • Manual Over-ride : Top Mounted Version, Side Mounted Version

DESIGN FLEXIBILITY :

  • The outlet flange is 45 Deg inclined to the axis of the valve.
  • These valves are available in two types of constructions, one the plug opens into the vessels & second the plug opens into the valve body.
  • These valves are available with actuators and manual operated.
  • Special temperature sensing arrangement within the valve body itself also can be provided.
  • Also the body can be provided with steam / oil / hot water jacketing arrangement to avoid solidification where in some application fluid tend to solidify at low temperature and discharged in hot condition only.
  • These valves are compact, lightweight design and ideal for inline maintenance under the tank.

DESIGN STANDARD :

  • Design Standard : ASME B16.34 & SFS EN 12516
  • Testing Standard : ANSI / FCI 70-2
  • Face to Face : As per manufactures standards
  • Flange Fitting : ANSI B16.5, 150#, 300# & 600#

ACTUATOR TYPE :

  • Pneumatic Diaphragm Actuator
  • Pneumatic Cylinder Actuator
  • Electrical Actuator

ACCESSORIES :

  • Pneumatic valve positioner
  • Electro – Pneumatic valve positioner
  • Air filter regulator
  • Solenoid valve
  • Limit switches
  • Proximity switches
  • Air lock relay
