Home Appliance Industry
- Duckbill Valves
For robotic vacuum cleaners equipped with an automatic self-cleaning function, excessive pressure can build up within the base station’s water tank when it is filled to capacity, preventing the discharge of surplus water and thereby creating a risk of hose or tank rupture. Furthermore, if the machine is inverted, gravity could cause water to leak out through the overflow port.
Our manufactured duckbill anti-overflow valves effectively resolve this issue for robotic vacuum manufacturers. These overflow valves facilitate the dis. charge of water through the overflow port when the tank is full, while simultaneously preventing water leakage from the port when the machine is inverted. Constructed from elastomeric materials and precision-molded, these duckbill check valves allow fluid to flow freely under positive pressure differentials while effectively blocking backflow under negative pressure differentials; they are widely utilized throughout the home appliance industry.
- Three Way Check Valve Reducer
Solutions are required to address specific challenges faced by home appliance manufacturers-specifically: when the outlet of an electric or gas boiler becomes clogged by timescale, causing internal pressure to rise to a critical level and risk pipe rupture; or when excessive pressure within a dishwasher’s water pump and moong lines causes water from the clean water tank to backflow into the detergent reservoir.
Our patented product-the Customizable Modular Three Way Check Valve Reducer-offers our clients a perfect solution to these issues. This three way check valve reducer features an integrated pressure relief mechanism that activates when internal boiler pressure reaches a predetermined threshold, venting the excess pressure to prevent pipe rupture. Furthermore, in instances of excessive pressure within the pump and mixing lines, the valve redirects the fluid flow through a relief port back into the piping system connecting the water tank and pump, thereby preventing backflow from the clean water tank into the detergent reservoir. While capable of withstanding high temperatures of up to 120°C, this valve also offers flexible customization options regarding interface dimensions and pressure relief settings. The unique three-port design effectively eliminates the need for multiple home appliances to utilize two separate single valves simultaneously, thereby conserving internal installation space.
Medical Industry
- Anti-siphon Check Valve
During intravenous infusion, the medication bag and the electric pump are often positioned higher than the patient’s infusion site. In situations such as an insecurely mounted fluid reservoir or a failure to close the flow-stop clamp during a fluid change, these specialized anti-siphon check valve effectively prevent the liquid situated above the valve body from flowing downward naturally due to gravity. The opening pressure range of these pressure activated valves can be customized; furthermore, the product has successfully passed rigorous testing-including a 3-year simulated aging test (verifying that the valve core does not stick) and comprehensive functional assessments-meeting all recommended product specifications. Having undergone extensive use and validation by numerous clients, the product has garnered widespread acclaim; its current annual production volume approaches one million units.
- Check Valve for Hemodialysis
In hemodialysis machines, the medication delivery tubing requires a mechanism to ensure that fluid does not flow backward. Consequently, a one-way valve must be integrated into the tubing system to facilitate unidirectional flow and prevent backflow. Check valves designed for hemodialysis primarily utilize screw-in or adhesive-bonded configurations. We currently collaborate with numerous domestic and international clients, ensuring the high-quality performance of our products. At present, the combined annual volume of these two specific medical valve models approaches the ten-million mark.
General Power& Garden Tool
- Lubricant Tank for Lithium-Powered Chainsaws
A client approached us at Rubber Valve seeking a custom-designed lubricant tank for a lithium-powered chainsaw. The client stipulated that the tank must guarantee absolute leak-tightness and safety, while its surface finish had to be free of burrs and black spots. Furthermore, the installation of the tank’s custom-shaped rubber tubing had to be spatially optimized, and the tubing itself was required to be highly resistant to both oil and bursting.
Ultimately, we manufactured the tank using PA6 material, thereby ensuring both leak-tightness and safety-qualities subsequently validated through relevant testing. For the oil tubing, we utilized NBR material; our design ensured a compact and uncluttered installation footprint while successfully meeting the client’s specific requirements for oil and burst resistance, thereby guaranteeing a smooth flow of lubricant. Additionally, we incorporated a duckbill valve to serve as the tank’s air intake valve; this component was engineered to prevent sticking due to aging and to ensure zero oil leakage during inverted vibration testing.
- Custom-Shaped Hoses
For battery-powered chainsaws, the oil hose must be designed to ensure smooth, obstruction-free operation while simultaneously guaranteeing a consistent flow of oil and overall safety. The client requested a custom-shaped oil tank hose capable of withstanding specific conditions regarding oil exposure and internal burst pressure. After conducting comparative production trials using various materials-including NBR, EPDM, and FKM—we successfully met the client’s specified standards and passed all requisite inspections. Our custom-shaped oil tank hoses can be tailored precisely to fit the internal spatial layout of specific chainsaw models. Furthermore, we offer customization options across a range of materials to satisfy diverse environmental requirements—such as varying levels of oil resistance, burst pressure tolerance, and low-temperature performance.
How to select a good Check Valve
- What information should I provide if I'm not familiar with check valves but need a suitable solution?
A: To help our engineers recommend the best check valve for your application, please provide the following details about your system and requirements:
1. Equipment: What type of equipment or system will the check valve be installed in? (e.g., medical device, home appliance, garden tools&general power, water purification, sanitary,)
2. Medium: What fluid or gas will pass through the check valve? (e.g., water, oil, air, corrosive chemicals, etc.)
3. Pressure:
①Cracking Pressure: The minimum pressure required to open the valve.
② Normal Working Pressure: The typical operating pressure of your system.
③Maximum Working Pressure: The highest pressure the valve may encounter.
④Reverse Pressure Resistance: The maximum/minimum pressure the valve must withstand in the reverse direction to prevent backflow.
4. Temperature & Humidity: What are the operating temperature range and humidity conditions ?
5. Flow Rate: What is the required flow rate (e.g., in liters per minute or cubic meters per hour) ?
6. Usage Frequency: How often will the valve cycle (open/close) during operation? (e.g., continuous, intermittent, or occasional use)
7. Service Life: What is the expected lifespan or number of cycles the valve should endure?
By providing these details, our engineers can evaluate your needs and recommend a check valve that ensures optimal performance, safety, and durability for your specific application.
