SIATA is one of the three brands of Pentair control valves, specifically developed in EMEA. Composed of a broad range of multiport composite valves with service flow rates up to 35 m³/h and advanced professional controllers, SIATA offers a full range of solutions that simplify the whole operating process on water treatment plants.

All products come equipped with both electrical and hydraulic connections, facilitating seamless integration with external commands. Notably, no additional interface or adaptation modules are required.


The key concept at SIATA is to offer valves that can be fitted with almost any controller depending on the customer’s needs and give several hundreds of individual configurations. Pentair engineers work closely with our customers to develop personalised solutions for their specific applications. The result is a unique combination of valves and related controllers for years of reliable and trouble-free service.

SIATA valves stand out for their distinctive features, making them particularly well-suited for applications such as softening, filtration, iron removal, de-alkalization, and deionization. These valves are crafted from recyclable engineering food-grade copolymers,this dedication to utilising environmentally friendly materials showcases Pentair’s commitment to sustainable and responsible manufacturing practices.



  • Design in glassfibre reinforced ABS
  • Various types of regenerant can be used
  • Inlet and outlet valves are double actuated
  • Either air or water can be used for valve control
  • The controller camshaft actuates the SIATA valves through the various regeneration phases

SFE is a performant, easy-to-use, and user-friendly controller, thanks to its LCD backlighted display and advanced programming options, including up to 4 regeneration phases with independently adjustable cycle times. It is perfectly suitable for all SIATA valves in our range for softening or filter applications.

  • Intuitive 3 push buttons, LCD display backlit during programming mode
  • Advanced programming capabilities
  • High frequency regeneration (every 1/2/3/4/6/8 or 12 hours)
  • Statistic mode


SFE-EV Pro is an intuitive, easy-to-use, and powerful controller thanks to its advanced programming options. Its programmable relays and useful
remote start signal dramatically increase its performance. Furthermore, the backlit LCD display can be customised and can accommodate a customer’s logo or company name.

  • Covers higher volume demand applications
  • Carry over of well-known SFE or SFE-EV functionalities
  • 3 free contact relays, each one programmable in 12 different mode
  • Ideal for customer specific applications
  • For duplex and simplex systems.


SFE-EV Viridion is the latest Pentair eco-friendly innovation featuring smart regeneration, providing users with an average water saving of 22%, possibly reaching 40% for some specific applications. This is made feasible thanks to the drain conductivity sensor, the variable brining function, and the adaptive reserve capacity, which all combined permit significant benefits and savings. Besides offering high customisation possibilities, this controller can manage SIATA valves V132, V230, V250 and V360 in softening versions.

  • Reduced water consumption (up to 23%) during regeneration
  • No chloride residuals in treated service water
  • Regeneration phases monitoring
