Lever Ball Float Steam Trap

The lever floating ball drain valve uses a floating ball to drive the valve disc to open and close with the rise and fall of the liquid level. 

Principle

¡ð Based on buoyancy and lever mechanical transmission

¡ð Density difference based on steam and liquid

Parameter

¡ð Rated pressure: PN40

¡ð Maximum allowable pressure of valve body: 3.92 megapascals/200 ¡æ

¡ð Maximum allowable temperature for valve body: 450 ¡æ/1.66MPa

¡ð Steam action test:>3 times/1.6 megapascals

¡ð Maximum working pressure: 3.2 megapascals

¡ð Maximum operating temperature: 350 ¡æ

¡ð Cold test pressure: 6.0 megapascals

¡ð Air test: 2.0 megapascals

Performance

¡ð The valve body and valve cover are made of cast steel, forged steel, and stainless steel

¡ð All internal components are made of stainless steel, which extends the service life of the drain valve

¡ð Special channel design to achieve zero water hammer

¡ð Adopting double balanced valve seat, with a long service life

¡ð Built in air exhaust valve to prevent steam lock

¡ð Built in filter enables the drain valve to operate in a clean environment

¡ð Back pressure rate up to 95%

¡ð The drainage plug is designed at the bottom of the drain valve to ensure that the internal water can be discharged and prevent the floating ball from being frozen and damaged in cold weather

Application

¡ð Large heat exchanger condensate outlet requires continuous and efficient drainage

¡ð Stable Drainage Control Point for Steam System of Paper Drying Cylinder or Drying Machine

¡ð Chemical plant distillation tower reboiler heat tracing pipeline condensate recovery area

¡ð Food processing steam jacket equipment requires high displacement hydrophobic positions

¡ð Key drainage nodes of low-pressure steam main pipeline and distribution network
