Features German technical agency optionally switching freely tee structure and stable performance balancing valve plug fully functional application of compressive shock straight trip diversion, the confluence of the electric control valve, three-way split, merge valve equipped with PS, 3810, ZAZ, DKZ series of straight travel electric actuator components. Within the servo actuator system without reprovision servo amplifier has an input control signal (4-20mADC or 1-5VDC) and single-phase power to control the operation to achieve the pressure, flow, temperature, level and other parameters adjusted using balanced valve plug structure, good valve plug stability, easy to produce vibration, low noise, allowing the pressure big, simple connection, which is widely used for flow coefficient, leakage relatively strict requirements of electric power, metallurgy, petroleum , chemical, environmental protection industries such as industrial automatic control system. Technical parameters structural principle: Three seater casting valve nominal diameter: 25-300mm Nominal pressure: PM1.6,4.0,6.4MPa Connection: Flange JB78-59, JB79-59 Body Material: HT200, ZG230-450 , ZG1Cr18Ni9Ti, ZG0Cr18Ni12Mo2Ti Normal temperature: -20 ℃ - + 200 ℃ heat dissipation type: -40 ℃ - + 450 ℃ gland forms: Bolt Clamp Packing: V-type PTFE packing, flexible graphite, stainless steel bellows valve body Format: Double-oriented two-seater sleeve type spool Flow characteristics: the percentage of properties and other linear features, quick opening valve body material: 1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti Actuator Type: Optional PS, 3810, ZAZ type (within DN100), DKZ type (DN100 and above) electronic linear actuators.
