Which Application Do You Need Your Solenoid Valve For?
With the newly developed Parker Solenoid Valve Series 201LG, use with aggressive and corrosive substances is significantly simplified. Especially for harsh applications in process technology, water treatment, as well as steam and acid applications. Major advantages are visible in the food industry for the production of olive oil, wine, and beverages in aggressive environments.
The valve body and coil can be selected and assembled by you. This offers significant advantages in designing the valve directly according to its application. Thus, in addition to various connection options, the nominal diameter and the suitable coil can also be selected. All components of the valve body are based on high-quality stainless steel with a standard built-in FKM seal.
Properties and Advantages of Parker Stainless Steel Valves 201LG
- compatible with 22 mm and 32 mm and ATEX solenoid coils
- very durable and solid construction
- for demanding applications with mechanical stress
- in connection sizes 1/8", 1/4", 3/8" and 1/2"
- Standard sealing material: FKM
- generally, two nominal diameters are possible for each connection option
- exceptionally generous flow values
- valve body, spring, armature tube, and magnet made of high-quality stainless steel
- Normally Closed (NC) and direct-acting function
- temperature range from -10°C to +140°C
- low power consumption of the solenoid coil
The 2/2-way pilot operated diaphragm valves are the best solution when control for media such as water, steam, and light oil is required. In operation, they only require a minimal differential pressure.
Based on solenoid valve technology, they are characterized by high volume flow, fast reaction time, and superior reliability, as well as their robust and modern construction. Options available include a mechanical manual override, which allows valve actuation without supply voltage, and a closing time regulation to prevent water hammer. Our water valves 7321B/7322B can be used in conjunction with most FCDE coils (including ATEX), low energy devices, and IP67 solenoid coils.
Technical Advantages of the Water Valves
- best performance at minimum and maximum differential pressure
- exclusive diaphragm construction for excellent volume flow, compared to competitor valves with the same dimensions and flat diaphragm design
- one of the fastest devices in terms of electrical and hydraulic opening time
- modular concept: better versatility of the valve thanks to the variety of available solenoid coils
- robust construction: areas exposed to mechanical stress have been studied and reinforced
- manual control option: the valve can be easily activated even when no power supply is available
- for pilot control, materials like stainless steel and special sealants are used to extend service life
- easy access to wear parts for simple and quick maintenance
These Parker brass solenoid valves are the ultimate solution for fluid control applications in professional coffee machines, espresso machines, water dispensers, and beverage dispensing machines. Especially when peak performance is required, as the valves are compact and robust at the same time. The stainless steel nozzle improves the service life of the valves and ensures more endurance and resistance to scale buildup and deposits.
Typical applications in beverage dispensers are:
- water level control of a boiler
- steam control
- cold, warm, and hot water shut-off
- mixing cold water and steam
- steam pressure regulation (pressure switch)
Areas of Application
In normal use, they serve to switch the supply of water, superheated water, or steam on and off in coffee machines or water dispensers. The valves are available in 2/2 and 3/2 configurations with standard pipe connections as well as flange plate mounting.
Properties
- connections in 1/8" and 1/4"
- also available as flange plate mounting
- 2/2 and 3/2 way configuration
- Seal: FKM-FDA / Ruby / EPDM
- Armature and nozzle made of stainless steel
- Valve body made of brass / nickel-plated brass
- reliable against limescale deposits
- robust construction and compact design
- improved service life
- good price-performance ratio
- different flow rates
- VDE and UL approval
The Parker LiquipureTM valve series is the ultimate solution developed by Parker Fluid Control Division Europe as a new standard for beverage dispensing machines.
For this new valve concept, lead-free materials were chosen in accordance with the strictest requirements and regulations and based on the expectations of people and markets regarding health-safe beverage dispensing machines. This new product group has NSF approval.
The parts that come into contact with the fluid are made of stainless steel. Maintenance is hassle-free thanks to the innovative design. Parker LiquipureTM valve technology is unique and protected by patent.
