Application

VDU series is a sanitary diaphragm valve with U type design, which is specially designed for using on food, beverage, dairy, brewing, pharmaceutical industries, etc. It is excellent for flow control as well as for open/close duties.

·Very useful at sampling / injection points on high purity systems

·Cavity free and self-draining

·Fully Autoclavable

·Hermetical separation of fluids from the operating mechanism by diaphragm

·Full traceability as per EN10204 3.1

·Various internal surface finish available each less than 0.40 Ra

·Reducing port is available

Materials

Body: AISI-316L
Membrane: EPDM+PTFE or EDPM

The seal materials comply with FDA177.2600 standard. Using proprietary technology, the diaphragm uses a combination of EPDM and PTFE, which is secured using SS bolts. The sealing part where contact with the medium is of PTFE material, it has good cold resistance -13℉ (-25℃), excellent heat-resistance 482℉ (+250℃), tolerance to most chemicals, and excellent abrasion resistance to medium flow.

Standard Design

Standards: DIN, SMS, ISO / IDF, BS / RJT, ASME / BPE.
End connections: butt-welded, sanitary clamp, or others upon request
Body type: T-type tee, U type tee, Mini type, tank bottom type, etc.
