Cvbp Series Backflow Preventers

Check valves are basically the type of valves which prevent the backflow of the fluid or gas traveling through that specific pipeline. The liquids or gases flowing through non-return valves flow in single direction mainly. These poppet check valves consist of two openings which mainly allows the fluid or gas to enter from one end and leave from the other end. If the flow turns and no check valve is installed, water hammer can occur. Water hammer often occurs with an extreme force and will easily damage a pipeline or components. Check valves are used in many different applications. For example they are often placed on the outlet side of a pump, to protect the pump from backflow. Centrifugal pumps are not self-priming, and therefore check valves are essential for keeping water in the pipes. Also, check valves are very often used in HVAC-systems (Heating, Ventilating and Air Conditioning-systems).

Check valves are two port valves i.e. two sides opened. Swing check valve allows unidirectional flow. From one side fluid enters and from other it leaves. These are automatic valves that do not require open and close assistance. As they have single directional functionality, thus, automatically prevents backflow or reverse flow. We at Suraj Steelmet maintain inventory of finished swing check valves at best competitive prices.

Duckbill check valves, widely used in the demanding applications of many industries, are precision-molded, one-piece elastomeric valves that provide reliable backflow prevention at low pressure differentials. Duckbill check valves allow free flow with positive differential pressure. With negative differential pressure, backflow is checked. Pressure drop across the valve is a feature unique to duckbill check valves. They can be designed to operate in a few millimeters (inches) of water to several hundred kpa (psi), depending on valve size, geometry and compound characteristics. Duckbill check valves are also designed to start functioning at specific opening and closing pressure ranges, depending on your specifications. •normally open one-way check valves •prevents backflow leakage when minimal backpressure is applied •can be installed easily into hole and sealed by compressing flange Duckbill check valve features: Reliable backflow prevention 100% elastomeric construction eliminates maintenance Will not corrode, warp or freeze open or shut 1”-2” cracking pressure, low head loss Curved bill enhances sealing around debris Custom built for each application based on pressure and flow conditions Available in diameters from 1/2" (12mm) to 96” (2400mm) Note: 1.

Wafer Type Lift Check Valve The wafer type lift check valve is suitable for the working temperature of -196~540, to prevent backflow of medium. According different materials, the wafer type lift check valve can be applied to various medium, such as water, steam, oil, nitric acid, acetic, strong oxidizing medium and urea in petrochemical, metallurgy, electric power, light industry and food industries. Different from flange type lift check valve, the wafer type lift check valve has characteristics of short structure length, small volume, light weight, small water hammer pressure, convenient installation, etc. Specification: ï,Size: 2~36 ï,Pressure Rating: Class150~2500LB ï,Main Materials: WCB, WC6, WCC, LCB, CF8, CF8M, CF3, CF3M, 4A, LF2, F304, F316 etc. ï,Design and Manufacture: API 594 ï,Face-to-Face: API 594, API 6D ï,Pressure-temperature Ratings: ASME B16.34 ï,Ends Connection: Wafer ï,Inspection & Testing: API 598, EN12266 Feature: ï,Safe and Reliable Sealing ï,Lug Wafer Type or Wafer Type ï,Lift or Piston Type ï,With Spring Simple and Compact

Oil And Gas Valves Oil and gas valves are crucial components of any oil and gas production facility, refinery or distribution system. Here are some of the most common types of oil and gas valves and their features: 1. Ball Valves: Ball valves are commonly used in oil and gas applications due to their high reliability and minimal maintenance requirements. These valves are designed with a rotating ball with a hole that allows or prevents the flow of fluids. 2. Gate Valves: Gate valves are commonly used in the oil and gas industry for on/off control of fluid flow. They are designed with a wedge-shaped gate that slides into the valve body to control the flow. 3. Globe Valves: Globe valves are used for various applications including isolation, throttling, and regulating flow. These valves have a disk that moves perpendicular to the flow of fluid to control the flow rate. 4. Check Valves: Check valves are designed to ensure that fluid flows in only one direction, preventing backflow. These valves are commonly used in pipelines and other critical oil and gas applications. 5. Butterfly Valves: Butterfly valves are designed with a disc that rotates around an axis to control fluid flow. These valves are commonly used in low-pressure applications where space and weight considerations are important. 6.Needle Valves: Needle valves are used for precise flow control of fluids. These valves have a small orifice and a tapered needle-shaped plug that provides accurate flow rate control.

SuperKlean's new DuraFlow spray nozzle with a hook was specifically designed to prevent accidental spray as well as allow the user the capability to hang the nozzle when not in service. Its unique cover design is not only durable, but also prevents the front mounted levers, which reduce hand fatigue and offer smooth lever action, from being accidentally activated when the nozzle is dropped. The new DuraFlow spray nozzles also come with a trigger locking mechanism for a safe and secure method of maintaining the nozzle open at any spray pattern. Variable spray patterns, adjustable from fan spray to solid stream, is one of the many features offered by the new SuperKlean DuraFlow spray nozzle. Water conservation is assured upon release of lever by the drip-free automatic shutoff feature. SuperKlean DuraFlow spray nozzles are available in 300 series stainless steel and weigh a total of 1.53 Lbs.
