Precision Flow Control for Mission-Critical Data Center Infrastructure

Engineering Reliability When Downtime Is Not an Option

In data center environments where every minute of downtime can cost hundreds of thousands of dollars, mechanical infrastructure must deliver absolute reliability. Griswold Controls has engineered hydronic valve solutions specifically to meet the unforgiving demands of mission-critical facilities, combining precision flow control, proven durability, and performance that protects uptime and optimizes total cost of ownership.

Proven Performance in Hyperscale and Colocation Environments

Since 1960, Griswold Controls has set the standard for innovation in precision flow control technology. Trusted by hyperscale and colocation data centers, critical healthcare facilities, top universities, and world-class hotels nationwide, the company’s solutions are deployed where thermal stability directly impacts business continuity.

Designed, manufactured, and assembled in the United States, every valve undergoes rigorous testing to meet exacting standards for durability, accuracy, and repeatability, requirements that are non-negotiable in 24/7/365 environments. Griswold Controls employs comprehensive testing methodologies utilizing both air and water pressure testing to detect leakage. Low pressure air testing at 30 to 50 PSI is just as effective as high pressure water testing at 150 PSI for finding leaks, while minimizing safety risks. Every valve is subjected to these stringent protocols, guaranteeing products arrive on site ready for reliable, leak-free operation.

Actuated Valve Platforms Engineered for Data Center Thermal Management

Griswold Controls’ Unimizer® and Streamline™ actuated valve platforms deliver precise temperature and flow control, high close-off pressure, and fast response to load changes. Proven reliability reduces failure risk while supporting continuous operation in demanding hydronic systems.

Pressure Independent Control: Maintaining Design Intent

PIC V® and MVP™ pressure independent control valves accurately maintain design flow regardless of system pressure variations. These valves eliminate over-flow that wastes pump energy, protect cooling coils, preserve delta-T, and combine balancing and control in a single solution. Performance remains consistent as loads expand without system rebalancing.

Material Science for Long-Term Reliability

In chemically treated chilled water systems, material selection directly impacts reliability. Griswold Controls’ brass products, QuickSet®, Isolator™ S, and PIC V®, use DZR (Dezincification Resistant) brass, providing superior corrosion resistance and preventing deterioration that leads to leaks and unplanned downtime.

Stainless steel components, including Uni-Flanges and Unimizer® valve bodies, deliver outstanding resistance to corrosion, chemical attack, and temperature variation, maintaining consistent performance over decades.

Serviceability and Total Cost of Ownership

Griswold Controls valves feature easy field servicing with replaceable cartridges that can be swapped without system shutdown, reducing maintenance downtime and lowering total cost of ownership.

Commitment to Sustainability and Green Building Standards

Griswold Controls has been a proud member of the US Green Building Council (USGBC) for over ten years, demonstrating the company’s commitment to sustainable building practices and energy-efficient HVAC solutions. The company’s products support LEED certification goals by optimizing energy performance, reducing water waste, and minimizing environmental impact throughout their operational lifecycle.

Optimum Solutions Through Partnership and Expertise

Griswold Controls’ goal is to offer a better product range and up-to-date application know-how that addresses the evolving challenges of modern HVAC systems. In cooperation with distributors and business partners, the company delivers optimum solutions for well-balanced HVAC systems tailored to each facility’s unique requirements. This collaborative approach ensures that data center operators benefit from both cutting-edge valve technology and the application expertise necessary to maximize system performance, efficiency, and reliability.
