Product details

Pneumatic Tilting Tank Bottom Discharge Valve is a pneumatic discharge valve specially installed at the bottom of reactors, storage tanks and pressure vessels. Adopting a tilting valve body structure, it forms a reasonable discharging angle between the valve flow passage and equipment bottom.

Driven by a pneumatic actuator, the valve plug can open or close rapidly to realize quick material discharge, shutoff and automatic control. The tilting flow passage reduces material retention and accumulation inside the valve cavity, making it especially suitable for high-viscosity, easily deposited, crystallizable media, as well as media containing solid particles or slurries.

Tank bottom discharge valves are widely used in chemical, fine chemical, pharmaceutical, food, dyestuff, pesticide, resin, coating industries and reactor discharging systems.

Working Principle of Pneumatic Tilting Tank Bottom Discharge Valve
The pneumatic tilting tank bottom discharge valve adopts a pneumatic actuator as the driving unit to control the valve stem and valve plug.Clean compressed air enters the pneumatic actuator to drive the internal piston, lifting or lowering the inclined valve plug via the valve stem.

  • Valve Opening: The actuator lifts the valve plug, fully opening the inclined straight flow path. Materials inside the reactor or tank are discharged by gravity.
  • Valve Closing: The actuator exhausts air (spring return for single-acting models), pressing the valve plug against the seat to cut off medium flow and achieve tight shutoff.

 

The inclined valve body connects smoothly with the tank bottom, minimizing dead space, medium sedimentation, crystallization and material buildup. Fitted with solenoid valves or positioners, it supports remote on-off control and flow regulation.

Product Specifications

Pneumatic Shut‑off Ball Valve are 0‑90° rotary valves. They utilize pneumatic actuators to convert compressed air into rotary motion, delivering fast and reliable valve opening and closing for industrial process control.
According to specific application requirements, pneumatic ball valves can be equipped with solenoid valves, limit switches, position feedback devices, air filter‑regulators, valve positioners and other pneumatic instrument accessories to realize automatic valve control and remote monitoring functions.
Many factors shall be considered when selecting a pneumatic ball valve, including valve size, pressure rating, operating temperature, process medium, flow rate, body material, seat material, actuator type and control mode.
If you are looking for a qualified manufacturer or supplier of pneumatic ball valves, please contact our technical team and provide your operating conditions. Our valve engineers will recommend suitable pneumatic ball valves, actuators and control accessories based on your specific application requirements. （Unit: mm）
