What is the material of the main parts of the butterfly valve?-(2)
Selection of valve sealing material: Sealing surface material: The sealing surface is the most critical working surface of the valve. The quality of the sealing surface is related to the service life of the valve. Generally, the sealing surface material should consider factors such as corrosion resistance, scratch resistance, erosion resistance, and oxidation resistance. Usually […]
What is the material of the main parts of the butterfly valve?-(1)
Selection of butterfly valve parts materials: There are many materials for manufacturing butterfly valves, including ferrous and non-ferrous metals and their alloys of different brands, and various non-metallic materials. The materials for manufacturing valve parts should be selected based on the following factors: 1. Pressure, temperature and characteristics of working medium. 2. The force of […]
Strainer valve introduction and its features
STRAINER VALVE, also known as filter: a device for filtering pretreatment. The filter valve is the filter equipment necessary for the use of hydraulic control valves and precise and easy-to-clog mechanical products. Strainer valve Introduction: STRAINER VALVE, also known as filter: a device for filtering pretreatment. The filter valve is the filter equipment necessary for […]
Daily maintenance and precautions of ball valves
Daily maintenance of ball valve: Long service life and maintenance-free period will depend on the following factors: normal working conditions, maintaining a harmonious temperature/pressure ratio, and reasonable corrosion data. When the ball valve is closed, there is still pressurized fluid inside the valve body. Before maintenance: relieve the pipeline pressure and leave the valve in […]
Applicable occasions and operation method of ball valve
Applicable occasions of ball valve: Since the ball valve usually uses rubber, nylon and polytetrafluoroethylene as the seat sealing ring material, its use temperature is limited by the seat sealing ring material. The cut-off effect of the ball valve is accomplished by pressing the metal ball against each other between the plastic valve seats under […]
Hard seal installation method of ball valve
Hard seal installation method of ball valve: 1) Remove the protective covers on both sides of the flange, and rinse and clean with the valve fully opened. 2) Before installation, the whole machine should be tested according to the specified signal (electrical or pneumatic) (to prevent vibration caused by transportation from affecting the performance), and […]
Installation instructions for ball valves
Installation instructions for ball valves: 1. Indoor devices or outdoor applications with protective methods; 2. Outdoor installations are corroded by wind, sand, rain, dew, and sunlight; 3. Have flammable, explosive gas or dust environment; 4. Humid tropical and dry tropical environment; 5. The temperature of the pipeline medium is as high as 450℃; 6. The […]
The parameter and troubleshooting of the ball valve
The parameter level of the ball valve: 1. Nominal pressure or pressure level: PN1.0-32.0MPa, ANSI CLASS 150-900, JIS10-20K; 2. Nominal diameter or caliber: DN6～900, NPS 1/4 ～36; 3. Connection method: flange, butt welding, thread, socket welding, etc.; 4. Applicable temperature: -196℃～540℃; 5. Drive mode: manual, worm gear drive, pneumatic, electric, hydraulic, gas-liquid linkage, electro-hydraulic linkage; […]
Product features and advantages of ball valve
Product features of ball valve: 1. The three-way ball valve adopts an integrated structure in structure, with a four-sided valve seat sealing type, fewer flange connections, high reliability, and a lightweight design. 2. The three-way ball core is divided into T type and L type, with long service life, large circulation capacity and low resistance. […]
Classification and characteristics of ball valve
There are different ways of classification of ball valves. Function classification: 1. Bypass valve: The ball valve is generally opened by static water, so the bypass valve is set to be pressed first, that is, both sides are filled with water; 2. Air valve: when filling with water, the buoy will automatically close the valve […]
