Special high-voltage operated valve dual phase steel

關(guān)注次數(shù):

所屬類別:Self-regulating valve

Dual phase steel special high-voltage operated valve seat (ZZYP), sleeve (ZZYM), double (ZZYN), three kinds of structure; actuator diaphragm, piston type two; type of action with pressure relief valve pressure regulator (B) and pressure relief valve before the pressure regulator (K). Nominal grade products are PN16, 40, 64; body diameter range of DN20 ~ 300; leakage levels are II, IV grade and VI grade 3 flow characteristics; for quick opening pressure regulation; from 15 to 2500Kpa. According to meet user needs combination condition.
Product features:
◇ self pressure regulating valve without any external energy, can in no electricity and no gas in the place of work, both for the convenience and save energy.
◇ pressure range and cross section thin, high accuracy of regulation.
◇ pressure set value during operation can be continuous set.
Regulation of the pressure after the valve, the valve before the pressure and valve after the pressure ratio of 10:1 to 10:8.
◇ rubber diaphragm actuator detection, high measurement accuracy, sensitive action.
Adopt the pressure balance mechanism, so that the valve is sensitive, accurate control.
