What is A Plastic Check Valve ?

- Plastic Check Valve is a valve made of PVC, uPVC, cPVC. The valve only allows fluid to flow through the valve in one direction and prevents the flow of fluid through the valve in the opposite direction.

- Plastic one-way valve or plastic one-way valve, plastic one-way valve is a type of one-way valve made of PVC, uPVC, cPVC, PPR plastic materials, making the valve resistant to chemical environments. , waste water, oxidizing environment, and salt water, sea water, waste water...

Technical Plastic Check Valves

- Size:  21mm to 110mm

- Body of Plastic check valve: PVC, uPVC, cPVC

- Connection ends: CNS, JIS, BS, ANSI, DIN

- Pressure range: 0 - 150 psi

- Temperature range: 0 - 120°C

Key Features Plastic Check Valve

- Light weight valve, easy installation, easy to disassemble.

- Strong corrosion resistance, is hygienic, non-toxic material.

- Suitable for a variety of liquids: water, air, oil, corrosive chemical liquids.

- Diverse in materials, connection types, designs, so it is suitable for many different piping systems.

- Smooth surface design, low friction, helps to increase flow rate and prevent the growth of microorganisms, algae

Advantages - Defect of Plastic Check Valve

• Advantages of Plastic Check Valve

- PVC plastic has excellent acid resistance, alkali resistance, corrosion resistance, so it is not affected by moisture and soil pH. Has excellent anti-corrosion and chemical resistance properties.

- Good pressure resistance

The valve also ensures safety because of its insulating properties.

- Slim valve design for easy installation, maintenance and repair

- Cost is relatively cheap

- Able to insulate, can block 95-97% of heat radiation from outside.

- Able to insulate, avoid the risks caused by electricity. Reduce the possibility of fire, electric shock, ensuring safety for people and the system.

- Temperature resistant up to 180 degrees Celsius (for PTFE plastic valves)

• Defect of Plastic Check Valve

- The valve has the disadvantage that it will be decomposed at high temperatures or oxidized in direct sunlight due to poor thermal conductivity.

- Cannot be used in systems with high temperatures such as hot oil, saturated steam. Decomposes at high temperature.

- Not resistant to high pressure because it is plastic, so it is not suitable for systems with high pressure above 25 Bar.

Application of Plastic Check Valve

- The valve has a plastic leaf that prevents the automatic backflow of water.

- Suitable for backflow prevention in swimming pools, spas, solar panel installations, industrial applications, aquaculture, agricultural irrigation and water pump installations.

- Preventing flooding of wastewater due to the phenomenon of high tides in wastewater systems of households and factories.

- Swimming pool: the water in the pool is circulated in a closed cycle. The treated water is put into the dirty lake from the lake to the water treatment system and is supplied to the lake. One-way valves are installed at the swimming pools. water inlet and outlet locations.

- When the pump stops working, all the fluid in the pipeline will flow back out through the suction port and completely lose the pump's priming water for the next operation. So the one-way valve is responsible for not letting water. flows back out.

- In addition, for buildings with a tank system on the roof, when the pump stops working, it will cause a water hammer phenomenon that can damage the pump and equipment system on the pipeline. The one-way valve is also responsible for preventing this water hammer phenomenon.

Types of Plastic Check Valves

Types of Plastic Check Valves

_____________________________________________

- Plastic Check Valve Swing Style

+ Plastic swing valve is a type of valve with an inner disc in the form of a flip door made from PVC, UPVC, CPVC, ... with many sizes from DN40-DN10). Suitable for multi-use aquatic environments and mainly used in small and medium-sized systems.
This type of valve works by the pressure of the fluid in the tube. When the fluid has not passed through the valve, it is closed by the gravity of the leaf plate, when the fluid through the valve creates pressure, pushing the valve blade upwards to help the fluid pass through the valve.

+ The feature is that it is possible to limit the phenomenon of water hammer causing damage to the rear equipment. The product has the highest price in plastic check valves.

- Plastic Check Valve Sping Style

+ Plastic spring check valve is a type of valve that opens and closes based on the elastic force of the spring made from PVC, UPVC,... Normally the flange of the valve will be closed to prevent the reverse flow of fluid, when it is stored. The material through the valve in the downstream creates a push on the flange, transmitting the spring force torque to create a space for the fluid to pass through the valve.

+ Size: dn15, dn20, dn25, dn32, dn40, dn50, dn65, dn80, dn100 for piping 21mm, phi 27mm, phi 34mm, phi 42mm, phi 48mm, phi 60mm, phi 90mm, phi 110mm.
