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: What does the J41Y-100I valve type mean?: Stop valve typeJ represents the cut-off valve, 4 (flange) on behalf of his connections, 1 (straight) on behalf of his structure, Y (seal) on behalf of his seat sealing surface or liner material code, 100 is the nominal pressure value, I (chrome molybdenum steel) is the code of the body material

Q: Ketem valve relative to other valve companies in the industry what are the advantages?: Floating hard sealing electric ball valve is suitable for two cutting and adjusting occasions. Connect the valve and actuator by using direct connection, DCL series miniature electric actuator (also can be configured according to user requirements of the electric actuator or pneumatic piston actuator of different types of electronic components and ultra short ball).

Q: What does valve J41H-16C mean?: J- stop valve4- flange type connection1- structure typeH- alloy steel seal16- nominal pressure 16 kgC- body carbon steel

Q: What are the types of valves?: 1.1 classification by purpose and functionx09 (1) cut-off valve is mainly used to cut off or switch through the media flow, including gate valve, globe valve, diaphragm valve, ball valve, plug valve, butterfly valve, plunger valve, ball plug valve, needle type instrument valve, etc.x09 (2) control valve is mainly used to regulate the flow of medium, pressure, etc., including regulating valve, throttle valve, pressure reducing valve and so onx09 (3) check valves are used to prevent backflow of media. Check valves with various structures are includedx09 (4) diverter valves are used for separation, distribution, or mixing of media, including distribution valves and traps for various structuresx09 (5) safety valves are used to protect the medium against overpressure. Various types of safety valves are included1.2 classify by main parameters

Q: Which direction is the valve? Which direction is it?: And we usually drink mineral water, drink bottles are in the same order

Q: What does the valve QF mean?: Valve type, one of the contents, Q refers to the ball valve, F refers to the F-4 seals.

Q: What's the sewage treatment valve with?: Sewage treatment system valve requirements are not high, the use of butterfly valve is one of the most cost-effective.

Q: What is the KVS in the valve parameter?: The Kvs of the valve reflects the passing capacity of the valve

Q: What are the general types of valves?: Pneumatic and hydraulic valvesPneumatic valve and hydraulic pressure based on a certain air, water or oil as the power source, using the cylinder (or cylinder) and the movement of the piston to drive the valve, the general pneumatic air pressure is less than 0.8MPa, the hydraulic or hydraulic pressure is 2.5MPa~25MPa. Such as used to drive diaphragm valves; rotary gas and liquid drives are used to drive ball valves, butterfly valves, or plug valves. The driving force of the hydraulic device is large, and it is suitable for driving large diameter valves. If used for driving plug valves, ball valves and butterfly valves, the reciprocating motion of the piston must be turned into a rotary motion. In addition to the cylinder or hydraulic cylinder piston to drive, but also the use of pneumatic film driven, because of its small stroke and driving force, it is mainly used for regulating valves.Manual valveThe manual valve is the most basic way of driving the valve. The utility model comprises a hand wheel, a handle or a plate hand, and is driven directly and driven by a transmission mechanism two kinds. When the starting torque of the valve is large, it can be driven by gear or worm gear to achieve the purpose of omitting. Gear drive, spur gear drive and bevel gear drive. Gear reduction ratio is small, suitable for gate valve and stop valve, worm gear drive is relatively slow, suitable for cock flashing, ball valve and butterfly valve

Q: How does the valve rust die?: Valve rust, and see what material, what type, the normal model iron, small, then change it directly. Large direct buy derusting lubricants, stainless steel just, then take the acid wash
