Inverted Bucket Steam Traps – Series E

Inverted Bucket Steam Traps belong to the family of mechanical traps. They operate on the difference in density between steam and water. MIYAWAKI offers a very wide range of inverted bucket steam traps for small up to large condensate loads. Inverted bucket steam traps discharge the condensate intermittently Application

Heat exchangers, dryers, unit heaters, sterilizers and other applications where condensate must be removed immediately

Super-Discharger

1. Incorporates the MIYAWAKI SCCV®-System 2. Double valve system with needle pilot valve and main valve 3. Operates by the pressure difference inside the valve unit 4. Makes the discharge capacity very large
5. Designed for high pressure up to 6,4 MPa (925 psig) – only for ER2

Features
All traps are equipped with stainless steel wear and corrosion resistant lever, valve and seat system for long and troubleless life

All valves and seats are lapped together

Traps of the series ER contains the patented SCCV® (Self Closing and Centering Valve) – System, which increases the lifetime of the valve and seat substantially

A small hole in the top of the bucket secures continuous automatic air venting

All traps are designed for quick and easy inline repairability

With stands high back pressure (up to 90%)
