300 Series – Telescoping & Butterly Valves

High-Performance 300 Series Water Control Products
Made in the USA since 1977

General Information

The 300 Series by Whipps, Inc. represents a pinnacle of innovation in water control technology, featuring both telescoping and butterfly valves designed for versatile and efficient performance across a variety of applications. Our series is engineered to address both standard and custom water management needs, offering flexibility and reliability in any environment. Whether you’re dealing with urban infrastructure, agricultural systems, or industrial processes, the 300 Series provides a robust solution tailored to your specific requirements.

At the heart of the 300 Series are our telescoping valves and butterfly gates, meticulously crafted to ensure exceptional durability and performance. Our telescoping valves offer the advantage of space-saving design and ease of operation, ideal for applications where space is limited but performance cannot be compromised. Complementing these are our butterfly gates, which feature a unique design that allows them to rotate 90 degrees with minimal effort, thanks to a sophisticated thrust bearing mechanism. This design not only facilitates smooth operation but also reduces the physical strain associated with opening and closing larger gates.

Each component of the 300 Series is constructed from premium, corrosion-resistant materials, including type 304/304L and type 316/316L stainless steel. These materials are selected for their superior strength and resistance to harsh environmental conditions, ensuring that our equipment performs reliably over an extended lifespan. The butterfly gates, in particular, are equipped with high-quality UHMW (Ultra High Molecular Weight) and rubber seals, providing a comprehensive seal around all sides. This design minimizes leakage and enhances the gate’s overall efficiency, making it suitable for critical applications where water control precision is paramount.

Whipps, Inc. stands out as an industry leader not only for our commitment to high-performance standards but also for our ability to deliver custom solutions. We understand that every application has its unique challenges and requirements. Therefore, we offer tailored solutions to meet your specific needs, ensuring that you receive equipment that perfectly aligns with your operational demands. Our expertise in custom manufacturing allows us to adapt our products to fit both standard and non-standard applications, providing you with the flexibility and reliability necessary for effective water management.

In summary, the 300 Series by Whipps, Inc. is designed to offer unparalleled performance and durability for a wide range of water control applications. Our focus on quality construction, advanced sealing technology, and customization ensures that you receive a solution that not only meets but exceeds industry standards. Trust Whipps, Inc. to deliver the high-quality, customized water control equipment that you need to achieve optimal results in your operations.

Product Advantages

Performance

Utilizing compressible seals provides superior leakage performance compared to traditional cast iron water control equipment with bronze seating faces.

Design Flexibility

All series 300 gates are custom-built for each application, allowing various mounting arrangements and a nearly unlimited range of sizes.

Corrosion Resistance

Painting or recoating stainless steel is not required to resist corrosion in water and wastewater.

Field Replaceable Seals

If the seals were ever to become damaged, they are easily removable and replaceable. In contrast, the bronze seating faces on traditional cast iron water control equipment cannot be replaced in the field

Looking for precision, reliability, and long-term performance in water level control? You’re in the right place.
In this video, we showcase the simple yet powerful mechanics of a Whipps, Inc. Telescoping Valve—a vital tool in managing fluid levels in treatment basins, clarifiers, reservoirs, and other water containment systems. Watch as the manual handwheel rotates to drive the stem, smoothly raising and lowering the slip tube to control liquid draw-off with accuracy and ease.
From stormwater to wastewater, Whipps telescoping valves are trusted for critical applications where durability, operator control, and cleanability matter most.
🔧 How It Works:
The telescoping valve is a manually operated water control device that allows adjustable withdrawal of liquids at various levels within a tank or basin. When the handwheel is turned, it rotates a threaded stem that vertically raises or lowers the inner slip tube. As the slip tube moves, it adjusts the elevation of the intake point—allowing operators to select which portion of the liquid column is discharged or retained.
This flexibility is especially useful in:
Decanting clarified water from settling tanks
Withdrawing surface water while leaving sediment undisturbed
Managing stormwater retention ponds
Controlling drawdown rates in water treatment processes
🌊 Why Choose Whipps Telescoping Valves?
At Whipps, Inc., we don't just build valves—we engineer solutions. Every telescoping valve we manufacture is custom-fabricated to meet the exact specifications of your facility and operational requirements.
✅ Key Features:
Robust construction using stainless steel or aluminum
Threaded or rising stem mechanisms for smooth, controlled movement
Manual or motorized actuation options
Slip tubes with adjustable locking for secure positioning
Low maintenance and long service life in demanding environments
Optional actuator mounts or floorstands for above-deck operation
Our telescoping valves are available in a wide range of sizes, materials, and configurations—and they’re backed by decades of proven performance across thousands of installations.
