Sanitary Diaphragm Valve
Application
YDPDV-1 series is a manual type sanitary diaphragm valve, which is widely used in food, beverage, dairy, brewing, pharmaceutical industries, etc. It is excellent for flow control as well as for open/close duties.
Materials
Steel parts: Stainless steel AISI 316L / 304 (forged and casting)
Diaphragm: EPDM + PTFE or EPDM
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° F (-25° C), excellent heat-resistance 482° F (+250° C), tolerance to most chemicals, and excellent abrasion resistance to medium flow.
Standard Design

Pneumatic controlNormally Closed (NC) - Air to open and spring to close;
Normally Open (NO) - Air to close and spring to open;
Air to Air (AA) - Air to open, air to close.
Optimal Installation Angle
Due to the structure feature, 15° ~ 30° Is the optimal angle for installation, which makes complete drainage after cleaning and keeps no residue.
