The most common types of valves used in data centers include butterfly valves, ball valves, gate valves, globe valves, and pressure relief valves, breather valves c/w flame arresters, non-return valve, fusible link valves, solenoid valves, balanced globe valves, and air vent etc,. These are used for pump rooms, cooling systems, diesel backup lines, fuel tank systems, and fire protection.
Pressure Relief Valves
Pressure relief valves are critical in maintaining system safety by automatically releasing excess pressure from pipelines, tanks, or closed systems. In data centers, they are commonly installed in chilled water systems, diesel fuel lines, and thermal storage tanks to prevent overpressure that could damage equipment or cause safety hazards.
Butterfly Valves
Compact, cost-effective, and ideal for large-diameter lines, butterfly valves are widely used in chilled water systems. They allow fast shutoff and are often motorized for integration with BAS (building automation systems). Phileda’s high-performance resilient-seated butterfly valves are engineered for long-term stability under fluctuating flow conditions.
Ball Valves
Known for their tight shutoff capabilities, ball valves are commonly installed in diesel fuel systems, backup water loops, and equipment requiring zero leakage. Phileda offers both manual and actuated options, suitable for low- and high-pressure applications with FM or UL compliance.
Gate Valves
Gate valves offer full bore flow when open and minimal pressure loss, making them ideal for main water and diesel supply lines. While not used for throttling, they are excellent for isolation in sections that don’t require frequent actuation.
Globe Valves & Balanced Globe Valves
For precise flow regulation — particularly in secondary loops, CRAC units, and coil circuits — globe valves are a preferred choice.
Fusible Link Valves
Designed for fire-critical applications, fusible link valves automatically shut off flow when ambient temperature exceeds a set threshold (typically around 72°C or 165°F). These are critical in diesel generator lines and fuel storage systems. Phileda is the only Chinese manufacturer producing these valves with FM/UL and API607 certification, ensuring compliance with international fire safety standards.
Breather Valves with Flame Arresters
Used primarily on diesel fuel tanks, breather valves allow safe venting while maintaining internal pressure integrity. When paired with flame arresters, they prevent external ignition sources from entering the tank. Phileda supplies ATEX-compliant assemblies suitable for explosive environments.
Non-Return Valves (Check Valves)
Preventing backflow is vital in chilled water pumps and fuel systems. A non-return valve ensures one-way flow, protecting equipment from reverse pressure damage. Phileda check valves are engineered for low cracking pressure and minimal head loss.
Solenoid Valves
Solenoid valves offer electrically actuated flow control — often used for emergency shutoff in fuel systems or integration with fire detection systems. These are fast-acting, programmable, and compatible with digital control environments. Phileda supplies explosion-proof and weatherproof solenoid valve options for outdoor or hazardous locations.
Air Vent Valves
Trapped air can impair heat exchange and lead to cavitation or corrosion. Automatic air vent valves remove air pockets from chilled water loops, especially during commissioning or after maintenance.
