Name: ZJHN seat control valve pneumatic membrane properties: fluorine pneumatic control valve pneumatic control valve (corrosion-resistant pneumatic control valve) ZMAPF46 lined pneumatic control valve (HEP Locator) ZMAPF46 lined pneumatic control valve (ZPD Locator) ■ Product Almost ZMAPF lined pneumatic control valve, pneumatic control valve corrosion is a corrosion through single-seat control valve, body wall and valve components in contact with the fluid are made of high-pressure injection molding process, lined with the ability to corrosion and aging of poly FEP (F46), and the use of PTFE bellows seal. Pneumatic lined valve widely used in acid, alkali and other strong corrosive media and toxic, volatile gases such as control of the liquid. Corrosion-resistant pneumatic control valve and its main features are as follows: 1, corrosion-resistant. Almost all of the media capability (including concentrated nitric acid and aqua regia) corrosion. 2, good sealing performance. Bellows and stuffing double sealed to ensure no leakage. 3, a small amount of leakage. Since the valve seat with soft seal, to ensure no leakage. 4, equipped with HA actuators, output power, compact structure. Product meets the GB / T4213-92. ■ The main technical parameters ● form through single seat valve body casting ball valve nominal diameter DN20 ~ 150mm Nominal PN1.6MPa Flange Standard GB / T9113, JB / T79 flange connection form (FF RF RTJ) gland type Bolt Clamp Operating temperature -40 ~ 180 ℃ packing V-type PTFE packing ● Trim valve in the form of single-seat piston-type (PTFE lined) is approximately equal percentage flow characteristic ● actuators and accessories, action in the form of Actuator name ZHA / B spring thin film multi-actuator Actuator Model ZHA / B-22 ZHA / B-23 ZHAB-34 effective area (cm2) 350 350 560 Stroke (mm) 10,16 25 40 spring range 1.5 ~ 3kg /cm2(0.15~0.3MPa) EPDM diaphragm material sandwiched nylon gas source interface RC1 / 4¨ Ambient temperature -30 ~ + 70 ℃ can be equipped with attachments locator, air filter regulator, to secure his position valve, limit switch , the role of valve position transmitter, hand wheel mechanism and other forms gas valve type (B) - when the loss of gas valve opening (FO); open air (K) - when you lose gas valve closed (FC) ■ Main parts material valve body, bonnet ZG230-450 lining F46 seat, plug 2Cr13 lining F46,304 F46 bonnet lining polyester fabric reinforced rubber sandwiched material PTFE bellows
