| Y945H/Y type electronic pair of valves seat steam relief pressure valve |
| Type of the products: Y945H/Y |
|
|
Structure characteristic and use :
This serial relief pressure valves are made up of such parts as valve body , valve seat , valve one ,etc. mainly, adopt one pair of valves seat , structure of one pair of awls body valve one. Adopt pressure balancing valve petal , is it regulate through valve petal pressure can mix or other type frank journey electronic carrying out device realize remote control and automatically control with ZKZ-BC type to go up and down.
The depression of this series of products is comparatively more suitable than to use 0.6.
This product is used in the steam pipework mainly , regulate the pressure. Apply to such trades as cogeneration of heat and power , light textile , printing and dye , petrochemical industry , making candies ,etc. extensively. |
