ZXP Type Top Guide Fine Regulating Valve 、Sleeve Valve

ZXP Type(Fine type)air-operating regulating valve, it assume small volume、light weight、precise、high-rate, It adopt ripe design technique and manufacturing empirical, It’s advanced product, It adapt to IEC standard. It’s widely used power station、metallurgy、chemical works、textile mill、glasswork and so on, It’s used auto-regulating and remote control in process of production

Products Description

l (a) and drawing 1 (b).

Valve Body、Valve Cap: HT200 ; ZG230-450 ZG1Cr18Ni9 Valve internal part: 1Cr18Ni9 (If need Special material or hardening, please call me). Fill Teflon、Flexible Graphite (a) Off drawing1 (b) On By course of different on-off mode ZXP type and ZXM type have two kind of air-closed type and air-opened type. The air-closed type valve consist of forward action and valve, When the input signal pressure be changed from lower value to upper valve, the valve is from full-opened to full-closed. The air-opened type valve consist of backward action and valve, when the input signal pressure be changed from lower value to upper valve, the valve is from full-closed to full-opened. It separately See drawing 1 (a) and drawing 1 (b). The air-operated many spring diaphragm actuator is short size、lightweight、simply installing. It consist of diaphragm、compress spring、salver、push rod、support、bushing、diaphragm cap and so on.

Main technical parameter of ZXP and ZXM type air-operated regulating valve

ZHA type air-operated many spring diaphragm actuator’s technical parameter

Technical Characteristic’s Index

The product except for aforesaid 1-4’s property, the other five item: endpoint deviation, tated travel deviation, tightness, compressive strength and appearance, according of GB4213“air-operated regulating valve standard technical conditions” to be tested. The nine item’s test standard execute GB4213“air-operated regulating valve standard technical conditions”

Other usage data

1.Working pressure and temperature At according to technical max working pressure to select nominal pressure of regulating valve, it must check condition of dielectric working temperature. Because nominal pressure is at the definite base temperature, it’s selected according condition of strength. If working temperature is over base temperature, The allowable max working pressure is sure to lower than nominal pressure. 2.Allowable pressure different To select regulating valve ought to note thrust angle except for considering other condition. The problem of the regulating valve normal working .It’s if the allowable pressure different is bigger than max working pressure different. In order to raise level of normalization、general、series of the regulating valve, Part of actuator and valve body have serial standard grouping. 3.Costiron、Steel regulating valve’s working temperature and max working pressure table.

Regulating Valve Installing 、Service and Keeping

(1)In the course of installing valve, ought to consider following list: a. Safety: In process of installing person and equipment’s safety. b. Control performance: The pipe system’s loss of pressure is in accord with counting regulating valve size’s loss ofpressure, to guarantee need flow characteristic. The valve connecting pipe has enough linear pipe. c. Installing position: Ought to enough space, it let operator manual operation and has installing and service’s place. d. A group of regulating valves: In general pipe system it install by-pass valve of cutting-off, It adapt to continuous with regulating valve. When to service regulating valve. close cutting-off valve, it use by-pass valve regulating. Drawing 2 is four kind of regulating valve’s group.

(2) The regulating valve is kind of précis instrument equipment, It can’t be collision and lest damage to note following terms: a. The valve must vertically install in the horizontal pipe, It ought to use support when it’s weigh is large and it’s installed vibratory site. b. The valve body ought to avoid over-stress by reason that the flange of pipe at two edges or equipment isn’t coaxial. c. Before the first installing and after the maintenance, we ought to pipe system before installing the regulating valve, or to install filter in front of valve. d. The direction of medium flow is as arrow direction of valve body.
