Product Description Product DescriptionSelf-operated Pressure Control ValveZZYP type independent pressure regulating valve without additional energy, the use of the medium itself pressure as power sourceto introduce the actuator control spool position,change the pressure difference and flow at both ends, so that before the valve(or after the valve) pressure stability. lt has the advantages of sensitive action, good sealing, small power of pressure setpoint wave and so on. lt is widely used in the automatic control of pressure relief and pressure regulation in gas, liquid andsteam media.Main Parts and MaterialsBody,BonnetWCB,304SS,316SS,316LSSCore,Seat1Cr18Ni9Ti, StellitePackingPTFE, Flexible graphite, Stainless steel bellowsSoft seal valve coreEnhanced PTFEGasketRubber asbestos board, 1Cr18Ni9Ti, Asbestos wound gasketMembrane coverA3Corrugated diaphragmNBR clip reinforced polyester fabricSpring60Si2MnStem,push rod2Cr13, 1Cr18Ni9TiBushing2Cr13 Self-operated Pressure Control ValveThis series of products have single seat(ZZYP), sleeve (ZZYM),double (ZZYN),three structures; Actuator has film type, piston type two kinds, The type of action is after pressure regulation for decompression valve (type B) and before pressure regulation for pressure relief valve(type k). The nominal pressure levels of products are PN16, 40,64; Valve body diameter range DN20 ~ 300; There are three levels of leakage:l,lV and Vl. The flow characteristic is fast opening; Pressure is segmented from 15 to 2500Kpa. Can be combined according to the need to meet the requirements of user working conditions.Suitable products and target prices Different industries, Different applications, Can recommend suitable products and target prices Please Goo >> >> Get the Latest Product Solution Quote >> Company ProfileCompany introductionGuangdong Yuantong Industrial Technology Co., Ltd. is located in Dongguan City, Guangdong Province, known as the world's manufacturing capital.

Which voltage of the electric actuator?DC24V, AC24V, AC110V, AC220VAC380V can be customized and DC12V is available for some smaller torque of actuator.2. What is the actuation time for electric actuator?It depends on the torque of actuator.The detailed timing would be as the following:·COVNA-05(50Nm)-20 seconds·COVNA-10(100Nm)/COVNA-16(160Nm)-25 seconds·COVNA-30(300Nm)/COVNA-60(600Nm)-60 seconds·COVNA-125(125Nm)/COVNA-250(2500Nm)/COVNA-400(4000Nm)-100 seconds.3. Can the actuation time be faster?Electric actuator can be customized the quick actuation gear,the soonest actuation time can be reach 10 seconds to open and close.4. What type of electric actuator you provide?ON/OFF type, Regulation type and Intelligent type.5. What is the difference from ON/OFF type, Regulation type and Intelligent type?1)ON/OFF typeON/OFF type is fully open and fully closed.2)Regulation type1.With input/output signal:4-20mA or 0-10V;2.Opening position of valve can be adjusted by signal;3.Available for PLC system.3)Intelligent type1.With input/output signal:4-20mA or 0-10V;2.Opening position of valve can be adjusted by signal;3.Available for PLC system.4.With display screen to acheieve site control.6. Can this electric valve be resettable (normally open / closed) automatically when power is removed?Our regular electric actuator can't be resettable automatically while power-off.But it can go to the multiturn electric actuator model with the extra electrical storage device along,which acheieve the valves can be automatic reset(normally closed) while power failure.7. Have the electric actuator had the presence of limit switches (contact about the position of the cut-off device)?Yes, there is the position indicator on the top of actuator.The open/closed status can be checked visually.8. Which type of protection class of this electric actuator?IP65, IP68, Explosion proof.9.Is there any manual override of electric valve?Yes, every electric valve includes the manual override.You can open/close10. Have the electric valve had the limiting operating time?Electric haven't had the limiting operating time.It can be working for 99 hours continually without getting heating.
