Specifications
 
 
 
sanitary pneumatic constant pressure valve/ pressure regulator/ pressure control valve
 
 
TECHNICAL PARAMETER:
Application:
This series valve is used to maintain a constant pressure of inlet or outlet.
The connection is flexible and with ideal mobility and cleaning performance. It is very easy to operate, maintenance, adjust.
 
 
Material:
material contact Steel parts:      Stainless 304\316L
valve core seal selection:a)soft seal:     EPDM. (standard)
                                                               SILICON, FDM, HNBR(CHOOSE).
                                               b)metal seal
 
 
Advantages:
Sealings:         Excellent acid-proof, alkali proof and high-temperature performance. a little degree of permanent compression deforms.
Investment forging valve plug: Pressure durability less than 1.2MPA,  metallographic structure better than casting ones.
Apparent design: Keep updated with international fashion style.
Cost performance: Impor substituted, cost saved and reliable operation.
 
Connection types:
 
Welded.
