Product Description

Product Description

Mushroom Valve – Unidirectional Flow Control Solution

Introducing the one-way umbrella valve, commonly referred to as Mushroom Valves, versatile elastomeric component designed for various applications. These valves serve as efficient sealing elements in backflow prevention devices, one-way valves (check valves), vent valves, pressure relief valves, and metering valves.

Engineered with precision, the one-way umbrella valve operates on a simple yet effective principle. When exposed to head pressure, it generates sufficient force to elevate the diaphragm from its seat. This pivotal action grants permission for forward flow, enabling unidirectional flow at a pre-determined pressure. Simultaneously, it acts as a vigilant barrier, promptly preventing any backflow in the opposite direction.

Choose the one-way umbrella valve for reliable, controlled flow in diverse industrial and fluid management settings. Its robust design ensures optimal performance, making it an indispensable component in systems where precise flow regulation and backflow prevention are paramount.

Applications of the One-way Umbrella Valve:

The one-way umbrella valve finds diverse applications across various industries, serving as a versatile component in critical systems. Key applications include:

  1. Automotive Fuel Tanks: This ensures efficient fluid control in automotive fuel systems.
  2. Inlet and Outlet Valves for Pumps: Used in both piston and diaphragm pumps for reliable one-way flow control.
  3. Check Valves in Breathing Masks: Employed as one-way check valves in disposable breathing masks, they ensure controlled inhalation.
  4. Medical Devices: Functions as a crucial element in medical devices, facilitating fluid control in healthcare applications.
  5. Home Appliances: Integrated into home appliances for fluid management, contributing to their reliable operation.
  6. Automobiles: Used in various automotive systems to regulate fluid flow and prevent backflow.
  7. Toys: Incorporated into toys for fluid control, enhancing interactive and functional features.

Advantages of the One-way Umbrella Valve:

  1. Simple Assembly: Easy to integrate into systems with no need for additional parts, simplifying the overall assembly process.
  2. Timely Sealing: Provides prompt and effective sealing, ensuring precise control over fluid flow.
  3. Corrosion Resistant: Built to resist corrosion, ensuring longevity and reliability in diverse environmental conditions.
  4. Wear Resistant: exhibits high resistance to wear, extending the lifespan of the valve and minimizing maintenance requirements.
  5. Position Independence: Functions reliably in various orientations, offering flexibility in installation.
  6. Cost-Effective: It offers a cost-effective solution for fluid control applications without compromising performance, making it a practical choice for diverse industries.

Installation Types of the One-way Umbrella Valve:

  1. Pull-in Type:

  • Description: Commonly used and ideal for manual assembly processes. In this method, the long tail is inserted through a central bore in the seat, and by pulling it, the valve securely pops into place.
  • Application: Suited for situations where hand assembly is preferred.
  1. Push-in Type:

  • Description: This type is advantageous when inserting a long tail through a central bore is challenging, such as in deep locations within a cylinder or inaccessible areas like the interior of a tank. It is also suitable for automatic assembly.
  • Application: Useful in scenarios where reaching the central bore is difficult or when the upstream side of the valve is not easily accessible.
  1. Belleville Type:

  • Description: The membrane of this valve resembles a Belleville spring washer and is hinged at the center with elastomeric material. Upon reaching a predetermined pressure, the valve rapidly opens. This design differs significantly from umbrella valves with inverted stems, which tend to be more restrictive.
  • Application: Well-suited for scenarios where a sudden and immediate valve opening is required. The central stem is positioned downstream of the valve and is secured by a retainer, which can be a separate component or an integral part of the device, such as a cap or lid located just above the umbrella valve. The seat of this valve type is simpler to manufacture due to having only one flow orifice.

These installation types offer flexibility in catering to various assembly requirements and specific conditions, ensuring the one-way umbrella valve is adaptable to a wide range of applications.

Materials Used in One-Way Umbrella Valves:

  1. Silicone, Fluorosilicone, and FVMQ:

    • Description: These elastomeric materials provide flexibility and resilience. They are suitable for a wide range of temperatures and offer excellent tensile strength, elongation, and abrasion resistance. Silicone, fluorosilicone, and FVMQ are commonly used in one-way umbrella valves for their versatility.
  2. EPDM (Ethylene Propylene Diene Monomer):

    • Description: EPDM is chosen for its outstanding performance in ozone aging resistance, weather aging resistance, and heat resistance. It ensures the longevity and durability of the one-way umbrella valve in various environmental conditions.
  3. HNBR (Hydrogenated Nitrile Butadiene Rubber), Buna N, and Nitrile Rubber:

    • Description: These materials excel in oil resistance, making them well-suited for applications where contact with oils is expected. HNBR, Buna N, and Nitrile Rubber contribute to the effectiveness of the one-way umbrella valve in scenarios involving oil-based fluids.
  4. FDA Food Grade and Medical Grade Materials:

    • Description: Umbrella valves crafted from FDA food-grade and medical-grade materials comply with Food and Drug Administration regulations. These valves are reusable and can operate within a broad temperature range (-40°C to 230°C). They exhibit superior tensile strength, elongation, and abrasion resistance compared to most organic elastomers. Silicone’s low-temperature flexibility is particularly advantageous.
  5. LSR (Liquid Silicone Rubber):

    • Description: LSR stands out for its ability to withstand extreme temperatures without altering its properties. Suitable for medical applications, it automatically withstands high-temperature sterilization. LSR is also effective in very cold environments.
  6. Fluorosilicone and FVMQ:

    • Description: These materials offer good oil resistance, strong acid resistance, alkali resistance, and antioxidant performance. Similar to silicone, they have a broad working temperature range (-40°C to 230°C), making them versatile choices for one-way umbrella valves.

The careful selection of materials ensures that one-way umbrella valves meet specific performance requirements, making them adaptable to a diverse range of applications and environmental conditions.
