With a differential pressure operating range of up to 800 kPa, it ensures precise temperature control and automatic balancing, making it ideal for applications with Fan Coil Units and Chilled Beams. Its compact design and compatibility with various actuators make it a versatile choice for modern HVAC systems. ## Description Frese Optima Compact Provides Modulating Control With Full Authority Regardless Of Any Fluctuations In The Differential Pressure Of The System. Frese Optima Compact Combines An Externally Adjustable Automatic Balancing Valve, A Differential Pressure Control Valve And A Full Authority Modulating Control Valve. Frese Optima Compact Makes It Simple To Achieve 100% Control Of The Water Flow In The Building, While Creating High Comfort And Energy Savings At The Same Time. An Additional Benefit Is That No Balancing Is Required If Further Stages Are Added To The System, Or If The Dimensioned Capacity Is Changed. Energy Saving Due To Optimal Control, Lower Flow And Pump Pressure. Maximized ∆T Due To Faster Response And Increased System Stability. Thread Size : 3/4Inch Country Of Origin : Denmark. ## Features - The presetting function has no impact on the stroke; Full stroke modulation at all times, regardless the preset flow. The constant differential pressure across the modulating control component guarantees 100% authority. - Automatic balancing eliminates overflows, regardless of fluctuating pressure conditions in the system. Compatible for almost actuators Thermic actuator On/Off or 0-10V, normally closed, Motoric actuator 0-10V, (Linear or Logarithmic) or 3 point control. - Differential pressure operating range up to 800 kPa High flows with minimal required differential pressure due to advanced design of the valve Small dimensions due to compact housing, - High comfort for the end-users due to high precision temperature control Longer life due to less movements of the actuator - Frese OPTIMA Compact pressure independent balancing & control valve (PIBCV) is used in heating and cooling systems in applications with Fan Coil Units, Chilled Beams or other terminal unit applications. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand Name | Frese | | Model Info | DN20 | | Package Dimensions | 5 x 5 x 3 cm; 150 g | | Part Number | DN20 | | Material Type | Stainless Steel, Brass | | Batteries Required? | No | | Item Weight | 150 g | ## Product Details - **Material:** Stainless Steel, Brass - **Brand:** Frese - **Inlet connection type:** PEX - **Outlet connection type:** PEX - **Maximum operating pressure:** 8E+2 Kilopascal ## Images ![Frese Optima Compact Pressure Independent Balancing & Control Valve 53-1338 3/4Inch, Dn20/Pn25 M/M High 5 P/T, Ac Chiller Water Actuator Valve, Made In Denmark - Image 1](https://m.media-amazon.com/images/I/61lAAqfv3iS.jpg) ![Frese Optima Compact Pressure Independent Balancing & Control Valve 53-1338 3/4Inch, Dn20/Pn25 M/M High 5 P/T, Ac Chiller Water Actuator Valve, Made In Denmark - Image 2](https://m.media-amazon.com/images/I/61YSWndU3vS.jpg) ![Frese Optima Compact Pressure Independent Balancing & Control Valve 53-1338 3/4Inch, Dn20/Pn25 M/M High 5 P/T, Ac Chiller Water Actuator Valve, Made In Denmark - Image 3](https://m.media-amazon.com/images/I/61uwno+TrwS.jpg) ![Frese Optima Compact Pressure Independent Balancing & Control Valve 53-1338 3/4Inch, Dn20/Pn25 M/M High 5 P/T, Ac Chiller Water Actuator Valve, Made In Denmark - Image 4](https://m.media-amazon.com/images/I/51nEG+rDJHS.jpg) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/327397134-frese-optima-compact-pressure-independent-balancing-and-control-valve-53](https://www.desertcart.vu/products/327397134-frese-optima-compact-pressure-independent-balancing-and-control-valve-53) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-11*
