Alfa Laval - SPC-2 regulating valves
Product Info
Supplier Info
since 2018
SPC-2 regulating valves provide accurate control of pressure, flow, temperature and liquid levels in tanks and stainless steel pipe systems used for hygienic processes in the dairy, food and beverage, and biopharm industries.
Features：
EXTREMELY ACCURATE VALVE FLOW REGULATION
Alfa Laval offers two regulating valves: the SPC-2 and a aseptic version, the SPC-2A. These normally open regulating valves provide highly accurate control of pressure, flow, temperature and fluid levels in tanks and in steel pipe systems.
ADVANCED HYGIENIC VALVE DESIGN
SPC-2 valves are ideal for high-volume sanitary process applications that require precision control. With a self-draining valve body, these valves are authorized to carry the 3-A symbol. Especially suitable for aseptic applications that require SIP (Sterilization in Place), the SPC-2 valves are fitted with PTFE diaphragms that prevent contamination from microorganisms and particles outside the product zone.
EXTREME VALVE ACCURACY
The SPC-2 features an electro-pneumatic actuator with integrated IP converter and integrated positioner, which contribute to greater operational accuracy and reliability. SPC-2 valves are IP-54 certified for water, dust and shock resistance.
SPC-2 VALVE RANGE
The SPC-2 is based on modular components that enable the selection of different plug configurations to meet specific requirements. Normally closed valves are available upon request.
ASEPTIC VERSION
The aseptic version of Alfa Laval’s SPC-valve is called SPC-2A. This is an electro-pneumatic modulating valve that features an IP converter as an integrated part of the actuator. Available with a range of plug designs with different Kv values, providing different capacities.
Supplied with a diaphragm that provides hermetic sealing against intrusion from the atmosphere, ensuring full protection against the effects of micro-organisms during processing.
This design allow aseptic control of pressure, flow, temperature in aseptic systems and to control the level of liquids in aseptic tanks.
Like all Alfa Laval valves, the SPC-2A is constructed with few moving parts housed in the actuator for added wear protection. Its compact hygienic design contributes reduces the need for maintenance and makes disassembly, if required, quick and easy. Plus there are no loose springs to pose any safety risk when opening the valve.
LOW MAINTENANCE REQUIREMENTS

COMPLIANCE WITH MOST HYGIENIC STANDARDS
Alfa Laval SPC-2 valves meet most standards requested in the dairy, food and beverage, and personal care industries.
How It Work：
CONSTRUCTIONThe SPC-2 valve consists of a valve body without seal, cone-shaped regulating plug, lip seal, bonnet and an actuator. The actuator with the bonnet is fitted to the valve body by means of a clamp ring. The standard valve is supplied with a standard normally open (NO) actuator. Upon request, it may also be supplied with a normally closed (NC) actuator. OPERATING PRINCIPLEAlfa Laval SPC-2 valves feature an electro-pneumatic actuator with an integrated IP converter, which provide accurate and reliable conversion of electrical signals from a controller directly to pneumatic signals. Signal conversion is extremely insensitive to pressure shocks. The pneumatic signals are relayed to an integrated positioner, which operates by means of the force balance principle. This ensures that the position of the actuator piston is directly proportional to the input signal. Signal range and zero point can be adjusted individually. By changing the standard measuring spring, the actuator may also be used for split-range operation. OPTIONS
