Check Valves- Ck-1

The Type CK1 Check Valves prevent backward flow of fluid in refrigerant suction, hot gas or liquid lines.

Parker’s CK1 check valves provide safe and effective backflow prevention for a variety of refrigeration applications. The gravity closing feature makes these valves ideal for systems that use a VFD or compressor unloading feature to reduce capacity as they can tolerate load fluctuations better than alternative check valve technologies. All CK1 check valves are flanged and have a manual opening stem for manual operation. The 20-32 mm (3/4 – 1-1/4”) port size valves have a PTFE seat; larger valves have a metal to metal seat. A minimum pressure difference of .03 bar (0.5 psi) is required to open the valve.

RS Valves

RS- Hand Shut- Off/ Expansion Valves

The RS Shut- off/ Expansion Valves were designed and built to maintain reliability both in their seating and back seating functions.

The complete Industrial Refrigeration line of Hand Shut-Off and Expansion Valves with bolt-on bonnets are designed and built to maintain reliability both in their seating and back seating functions. This entire line is supplied with stainless steel stems for maximum corrosion resistance and back seating capability. A unique carbon filled PTFE seat is standard throughout the line, lending durability to the seating surface. In addition, a dual O-ring stem packing design along with a stem packing seal is standard on all valves 1⁄4” thru 12” (Shut- Off) and ¼” thru 2” (Expansion). This innovative design seals both the valve stem and bonnet bore with independent O-rings, which are captured in a carbon PTFE carrier. The addition of the packing provides for backup sealing capability in the unlikely event of an O-ring failure. A packing nut design with either 1⁄4” or 5⁄16” flats provides a generous wrench engagement area, with little likelihood of “rounding” the flats. With the O-ring cartridge used in all valve bonnets, there will typically be no need to loosen the packing nut when opening or closing a valve. In most cases, stem resistance will be negligible, allowing the valve to be easily repositioned.

The extended bonnet is available for globe style valves in the Tee body configuration and in angle style bodies. Valves are available with either hand wheel or seal cap. These caps are exclusive to this series of valves and should not be exchanged with seal caps from other R/S service valves.

• Industrial Refrigeration

Semi Welded Plate Heat Exchanger

Alfa Laval Industrial semi-welded line handles most refrigerants and is particularly suitable for applications involving ammonia. Semi-welded heat exchangers are used in both organic and inorganic chemical processing when the chemicals involved limit the selection of gaskets that can be used or when the required design pressure makes fully gasketed plate-and-frame heat exchangers insufficient.

The media passes through the welded channel facing the ring gasket sealing between the laser welded cassettes. Alfa Laval semi-welded heat exchangers employ the Alfa Laval RefTight™, a unique sealing system which guarantees high performance by positioning the laser weld on the outside of the ring gasket groove. The smooth ring gasket grove ensures equal sealing force over the entire porthole gasket.

Equipped with well-designed features, Alfa Laval Industrial semi-welded line of heat exchangers are easy to maintain and have a long service life. Some of the features available include:

  • ClipGrip™ gasket – a glue free gasket with superior alignment that ensures a perfect seal and trouble-free maintenance.
  • Glued gasket – two-component, oven-cured epoxy glue keeps the gasket in place during any possible cleaning condition.
  • CurveFlow™  distribution area – ensures full use of the heat transfer area and minimizes fouling.

How it works  plate flow semi welded plate exchanger Alfa Laval Clark Johnson Co

The heat transfer area of a gasketed plate-and-frame heat exchanger consists of a series of corrugated plates, assembled between the frame and pressure plates, which retain the design pressure. For the highest thermal performance and to enable a very close temperature approach, fluids normally run counter-currently through the heat exchanger.

The sealing between the plates on the Industrial semi-welded line alternates between laser welds and gaskets.  The laser welded channel allows use of fluids that are not compatible with normal gaskets and also allows for higher design pressure than fully gasketed plate-and-frame heat exchangers. Additionally, the Alfa Laval RefTightTM sealing system guarantees equal sealing force over the entire porthole gasket.

Industrial semi-welded line is available with various pressing depths and angles of the chevron pattern and various shapes of the corrugation which are carefully designed and selected to achieve optimal performance. The CurveFlowTM and the chocolate pattern distribution area are two design features available that ensure fluids are evenly distributed across the entire plate.  The result is that the entire heat transfer surface is fully utilized and stagnant zones that can result in fouling are avoided.

High flow turbulence between plates results in higher heat transfer; however, the consequence is pressure drop. Our thermal design engineers will help you design and select the model and configuration that is suitable for your application needs while delivering maximum thermal performance and minimizing pressure drop.

The Industrial semi-welded line can be configured in many ways. The animation shows single pass configuration of a fully gasketed plate-and-frame heat exchanger. The flow principle of a semi-welded heat exchanger is the same. The difference is that every second channel is sealed with a laser weld instead of a gasket. Multi pass with 2 or more passes on each side is also possible.

Highly efficient with unique sealing system

Alfa Laval industrial semi-welded gasketed plate heat exchangers are suitable for liquids and gases incompatible with normal gaskets or at higher pressures. Commonly used in refrigeration applications for evaporation and condensation of ammonia and CO2.

The unique Alfa Laval RefTight™ sealing system guarantees a long life-time sealing between the welded channels because the laser weld is on the outside of the ring gasket groove. The smooth surface ensures a tight uniform seal over the entire gasket ring.

What make our plate heat exchangers so reliable, efficient and serviceable?

Equipped with well-designed features that make a difference, Alfa Laval Industrial semi-welded line of heat exchangers are easy to maintain and have a long service life.
