Duckbill Check Valves

Duckbill Check Valves

Duckbill check valves allow flow in only one direction through a pipe or tube while preventing any backflow in the opposite direction. When fluid pressure is applied from the upstream side, the duckbill flexes open to allow flow. But if pressure comes from the downstream side, the duckbill flaps seal shut to block reverse flow.

Typical applications for duckbill check valves include:

  • Preventing sewer and septic tank backflow
  • Inline pump protection
  • Sprinkler and irrigation systems
  • Drainage and flood control

Duckbill valves' simple, passive operation offers reliable backflow prevention without needing manual intervention, a power source, or maintenance. The elastomeric duckbill is the only moving part. Its flexing action allows it to seal around solids, making it resistant to clogging compared to other check valve designs with hinge mechanisms that can jam.

Duckbill valves find wide use across industrial, municipal, and commercial sectors due to their simple and reliable operation, compact size, and low cost compared to mechanical check valves. Some of the most common applications include:

  • Wastewater and stormwater management: Duckbill valves are extensively used in sewer lines, septic systems, and stormwater outfalls to prevent backflow of contaminated water during heavy rains or floods. They are less prone to clogging than flap valves.
  • Irrigation and agriculture: In sprinkler systems and agricultural pipelines, duckbill valves maintain consistent flow direction and prevent pump prime loss. They also inhibit dirt, rodents, or other foreign materials from entering pipes.
  • Marine and aquatic systems: Duckbill valves are used in boat bilge pump discharge lines, live fish holding tanks, and pond aeration systems. Their unobtrusive profile minimizes flow restrictions.
  • Industrial processes: In chemical processing, printing, and manufacturing operations, duckbill valves control gases and liquids, vent tanks and pipelines, and isolate pressure gauges and instruments.

Compared to traditional swing check valves or spring-loaded poppet valves, duckbill valves offer several advantages:

  1. No mechanical hinge or spring to fail or wear out, giving them superior reliability and service life.
  2. Low cracking pressure and high flow rate due to streamlined design.
  3. Tight sealing even around suspended solids and minimal leakage.
  4. A simple one-piece elastomer duckbill is inexpensive to manufacture and easy to replace.
  5. Various elastomer choices to suit corrosive chemicals, high temperatures, or food grade needs.

Duckbill check valves' versatility, dependability, and low maintenance requirements make them a popular choice across diverse industries for providing economical, trouble-free backflow prevention and fluid control. While not suited for every application, they offer an elegant solution in many common fluid handling scenarios.

What Are Temperature Control Valves and Temperature Regulators?

What Are Temperature Control Valves and Temperature Regulators?

Temperature control valves and temperature regulators, often known as TCVs, actively maintain the temperature of a process. They achieve this by regulating the pressure or flow of thermal fluid in various components such as compressors, tank jackets, and heating coils. These devices are essential in processes requiring stable temperatures unaffected by fluctuations in the surrounding environment.

Temperature regulators fall into two main categories: self-actuated and externally actuated. Self-actuated temperature regulators operate independently without the need for an external power source. They use a thermally sensitive material that expands and contracts in response to temperature changes. This expansion and contraction drive the actuator, adjusting the valve's position and altering the flow path of the thermal fluid toward the heating element. This mechanical actuation provides precise temperature control, particularly suitable for applications where the setpoint remains constant and does not require frequent adjustments. Additionally, self-actuated temperature regulators offer a cost-effective solution for effective temperature management. These regulators are also known as self-operated temperature regulators.

Externally actuated temperature control valves often play a critical role in complex control systems, integrating an external temperature sensor and a Proportional-Integral-Derivative (PID) controller. These valves necessitate an external power source for operation. In a typical setup, the operator sets a desired temperature on the PID controller, continuously receiving feedback from the temperature sensor monitoring the process. The PID controller then compares the set temperature with the actual process temperature reported by the sensor. Based on this comparison, it sends an electronic or pneumatic signal to the temperature control valve, instructing it to adjust its position. This adjustment ensures the maintenance of the process temperature at the set point. This type of valve is beneficial in applications requiring frequent adjustments of temperature set points for automation purposes.

How Does the Jordan Valve Mark 80 Series Temperature Regulator Function?

The Jordan Valve Mark 80 Series Temperature Regulator operates independently, eliminating the need for an external power source or costly additional instruments. This self-sufficiency is due to its unique design: the actuator connects to a sensing bulb via a capillary system containing a volatile fluid. When this fluid heats up, it vaporizes, creating pressure within the system. This pressure acts on the diaphragm, prompting the valve to open (in reverse-acting models) or close (in direct-acting models). The Mark 80 Series, featuring a seal welded actuator (SWA), results from extensive research, ensuring the most accurate temperature control. When paired with Jordan Valve's sliding gate valve technology, the Mark 80 regulator achieves superior control. For added versatility, it allows field adjustments of the set point and can accommodate different temperature ranges without removing the valve from its installation.

The Jordan Valve Temperature Regulator Series also presents various self-operated regulator configurations to cater to higher flows, fail-open or fail-close settings, tracing lines, and pilot operations.
