Butterfly Valve 

 

1. Brief Introduction

Soft Seal  butterfly valve is my company under current domestic FGD system design products. 

To meet the limestone and gypsum slurry grout corrosion, and the calve stem plate using a special corrosion-resistant alloys, high-valve seat wear rubber meet the large number of suspended particles in the liquid on the valve seat erosion. Therefore products with high wear-resistance and anti-corrosion of high. The product is designed to address user requirements, targeted and high reliability. Suitable Mediums: Lime cream, sulfur dioxide, lime slurry paste, process water and other corrosive media.

Q:Automatic exhaust valve installed in the pipe before and after the installation of other valves need to press it?
In general, the exhaust valve (large diameter) and a maintenance valve, normally open,
Q:What's the difference between valves and valves without valves?
The advantage of carrying valves and venting valves is that they control the amount of exhaust and prevent other fluids from flowing out.
Q:Which valve can play a good regulatory role?
A wide range of valves, the function is different, although like conventional butterfly valve, ball valve can play a regulatory role, but their role is not linear, so if you need to adjust the precision of the valve, it is best to select the control valve.
Q:What kind of industry does valve belong to?
Valves are machinery and industry equipment;Valve belongs to general mechanical equipment
Q:How can the material be checked by valve approach? What experiments do you need?
First of all, to check material certification, and secondly, the material appearance, shape and size of the initial test, again on the alloy material according to the standard spectrum analysis, the valve to do pressure test.
Q:Valve legend
F means the initial letter of the valve, which is shown as a stop valve
Q:What items and detailed procedures should be inspected for valve size inspection?
Internet access can be downloaded, such as free standards to share and download sites. If you need any other valve standard, send me the mailbox.
Q:The water pipe in the house is broken.
In general, a unit has a total valve. From this start, find it, find a less water when passing the total valve home to change, more energy, save trouble later. Or find the person of the company to deal with tap water.
Q:Why is copper used in cryogenic valves?
The rigidity of copper is better, and the friction parts are not easy to produce adhesion. The influence of temperature on copper is smaller than that of steel. Especially in the valve stem, there is also the important gear part, copper!
Q:How can the valve actuators be classified?
