Check Valve
The Best of Industrial Valves & Pressure Gauges 101
Valves are an integral part of the day-to-day functions- plumbing valves used in taps for hot and cold water, gas control valves on cookers and barbecues, small valves fitted to washing machines and dishwashers, and safety devices fitted to hot water systems.
Valve is a device that regulates the flow of gases, fluidized solids, slurries or liquids by opening, closing or partially obstructing various passageways. Industrial Valves are used in a variety of commercial, residential, military applications, and also in transportation. Oil and gas, power generation, mining, water reticulation, sewerage and chemical manufacturing constitute the majority of valves used by industry. These may be operated manually, or automatically, driven by changes in pressure, temperature or flow. Based on the varying needs, valves may be of different types.
- A eck valve llows fluid to flow through it in only one direction. Check valves are two-port valves, that is, they have two openings in the body, one for fluid to enter and the other for fluid to leave.
- Ball Valves are principally designed as on/off isolation valves for a wide range of temperatures and pressures; they have inherent quick opening flow characteristics. Specially designed ball valves however, may offer good flow control capabilities at high pressure.
- Butterfly valves are for quick turn on or shut off applications including agricultural and irrigation, water distribution and waste treatment. Industrial applications including chemical, paper and pulp, and a wide array of industrial mediums.
- Gate valve are commonly used in many garden, irrigation, and industrial flow control systems.
There are a wide range of industrial applications in which Pressure Gauges are utilized. Pressure Gauges are designed to measure the pressure of a gas or liquid. These instruments monitor and indicate the internal pressure and/or vacuum of vessels and systems, especially those having dynamic working characteristics that require regular monitoring. These vary in style, size, pressure ranges, and wetted parts material, depending on the application. Specialty tanks, such as fire extinguishers and medical gas cylinders use pressure gauges. The important types include:
- Liquid Filled Pressure Gauges can be filled with various fluids, such as silicone oil, mineral oil and glycerin. The liquid filling provides protection to internal components of the gauge in severe environments in which the gauge may endure excessive vibration and pulsation. Gauges made of stainless steel can be used in corrosive environments or in applications that have strict sanitary requirements and are capable of withstanding high pressure cleaning.
- Industrial Pressure Gauges have heavy-duty sensing elements and case designs and higher accuracy requirements than general purpose utility gauges, and are built for extended life, designed for harsh, corrosive environments.
