The new “Apollo”® Valves LD151 Resilient-Seated Butterfly Valve represents a significant advancement in butterfly valve technology, engineered to meet the increasing demands of industrial, commercial, mechanical, and data center applications.

Built as the next evolution of the proven LD141 series, the LD151 platform delivers higher pressure capabilities, improved sealing integrity, simplified product management, and full compliance with today’s industry standards.

For engineers, contractors, and facility operators seeking durability, reliability, and performance, the LD151 is designed to exceed expectations.

Higher Pressure Rating for Broader Applications

Today’s systems, especially in mission-critical environments like data centers, require valves that can perform under higher pressure conditions without compromise. The LD151 series delivers a 250-psi pressure rating up to 24 inches, expanding its suitability across:

Data center cooling systems

Commercial mechanical rooms

Industrial processing systems

High-demand HVAC applications

This enhanced pressure capability ensures compatibility with modern high-performance system designs while maintaining the durability professionals expect from “Apollo”® Valves.

Designed for Data Centers and High-Demand Mechanical Systems

As data center construction accelerates and mechanical systems become more robust, valve performance requirements continue to rise. The LD151’s 250-psi rating and enhanced sealing design position it as a strong fit for:

Chilled water systems

Cooling tower loops

Mechanical distribution systems

High-pressure HVAC installations

Its improved durability and simplified product lineup also make it a practical choice for large-scale projects requiring repeatability and reliability.

Superior Vulcanized Seat Design for Enhanced Sealing

At the heart of the LD151 upgrade is its vulcanized (bonded) seat design, a major improvement over traditional field-replaceable seat configurations. This advanced seat construction provides:

Improved sealing integrity

Stronger performance in bi-directional dead-end service

Increased durability and lifecycle reliability

By bonding the seat directly to the valve body, the LD151 reduces the risk of seat movement, leakage, and premature wear—delivering dependable long-term performance in demanding environments. For contractors and facility managers, that means fewer maintenance concerns and greater operational confidence.

Full Compliance with Industry Standards

The LD151 Series meets or exceeds key industry certifications and standards, including:

MSS SP 67

API 609

ANSI/FCI 70-2 Class VI

AWWA C504 & C550

NSF/ANSI 61 & 372

ISO 5211 top plate actuator interface

These certifications ensure that the LD151 resilient-seated butterfly valve is suitable for a wide range of applications, including potable water systems, commercial HVAC, and industrial process environments, while maintaining compatibility with automated actuation systems.

Engineered for Long-Term Value

The “Apollo”® LD151 Resilient-Seated Butterfly Valve is more than a product update—it’s a strategic evolution. By combining higher pressure capability, enhanced sealing technology, simplified SKU management, and full industry compliance, the LD151 is engineered to support modern mechanical systems with confidence.

For engineers specifying high-performance valves, contractors installing complex systems, and distributors managing inventory efficiency, the LD151 delivers measurable advantages. The next generation of resilient-seated butterfly valves is here—and it’s built for what’s next.
