Dimensional Requirements

Duplex Filter Large

These large duplex filters employs a simple rugged and positive method for change-over, using two disc valves operated by screwed shafts. The internal screwed portion of the operating shafts are sleeved, totally enclosed and protected from liquid. As standard the operating shafts are interconnected with the help of chain for simultaneous operation and are provided with a valve position indicator showing which chamber in on stream. These filters are also fitted with quick release cover.

Materials :



Flanges : Cast Iron – ANSI.B 16.5 Class 250 FF
Drilling : Drill hloes can also be done as per customer’s specification

Fabricated “Y” Type Strainer

Strainers take their name from their configuration. They are typically used in application where the amount of solids to be removed is small, and where frequent clean – out is not required. They are most commonly used in pressurized lines, water or oil, but can also be used in suction.
A Y-Strainer has the advantage of being able to be installed in either a horizontal or vertical position. However, in both cases, the screening element must be on the “downside” of the strainer body so that entrapped solid can be properly collected and held for disposal.
A blow down plug on the drain port will allow clean-out without removal of the screen, and without interrupting the process flow.
Size of the screen as well strainers can be fabricated as per Design requirement.
Features :
Machined, tapered seat ensure a perfect fit for removable, stainless steel screen.
• Covers furnished with blow off tapping
• Heavy gauge perforated stainless steel normally furnished with spot welded seams. For exceptionally fine straining,
perforated screens are lined with wire mesh.
