Bottom outlet valve

Built specifically on request by the customer, this special type of valve is designed and realized to be applied to the bottom of the tanks for the drains in presence of critical temperature, pressure and abrasive products. The project, with an installation totally flat, limits the residual that may remain in the nozzle of the drainage.

Our bottom tank ball valve has a geometric design that allows a smooth flow and prevents stagnating of the media.

Bottom outlet floating type

Technical specifications

Our bottom valves offer the best solution where minimum dead space between ball and tank is required, where media could stagnate at the tank outlet and where full blending of reactor volume is imperative.

Valve application

  • Filter dryer
  • Vacuum dryer
  • Stirrer vessel
  • Transport vessel
  • Reactor
  • Other vessels

Materials

  • Asteroid
  • 316
  • Other materials on request

Features

Advantages

This type of valve has several ddvantage over a conventional tank bottom valve, as:

  • Higher CV
  • Direct flow
  • Simple quarter turn operation (easy automation)
  • Low weight and compact
  • Easy maintenance
Low sump area

By the use of an angled stem design and the direct mounting to the vessel bottom flange, the Bremer bottom outlet ball valve ensures flush fitting with the vessel inner bottom.

  • No accumulation of product between valve ball and vessel inner bottom
  • Improvement of product mixing in stirrer vessel
  • Reduction of efflorescence and product agglomeration
  • Avoiding false samples
Cavity free

The usual cavity between ball and housing in non-cavity-free ball valves give cause for disturbance because residual products can crystallize, polymerize and so affect the function.

  • Clean, non-false product
  • No sediments of expensive products in the ball valve housing
Angled stem design

Because of the further distance from the actuator mounting flange to the vessel, it makes the automation of the ball valve and isolation of the vessel very convenient.

  • Easy automation of ball valve
  • Easy isolation of vessel
  • Flush fitting of ball valve with vessel inner bottom
Direct mounting to vessel flange

The ball valve is mounted directly using screws or bolts to the vessel flange. Direct and easy assembly of ball valve to the container flange. On request, our bottom  outlet valves may be executed:

  • In special alloys
  • With sampling ball
  • With heating jacket

test

Bremer tests and certifies all valves according to API598, BS6755 part I or DIN3230. Upon request Bremer can perform all the following additional tests, internally or using:

  • High Temperature Test
  • Low Temperature Test
  • Vacuum Test
  • Cycle Test
  • Nitrogen Hight Pressure Gas Test
  • Fugitive Emission with Helium
  • Dye Penetrant Test
  • Magnetic Particles Test PMI
  • Ultrasonic Test
  • RX Test
