Product Introduction

The high performance butterfly valve (also known as a double offset butterfly valve) features an innovative design that offers rugged reliability and extremely easy maintenance in the field. Independent and long service life capability, with zero leakage shutoff.

A high-performance butterfly valve is a type of valve that is designed for high-pressure and high-temperature applications. It typically features a metal seat and a metal disc mounted on a shaft, which can be rotated to control fluid flow through the valve. The design of a high-performance butterfly valve allows for precise control of flow rates, and it is often used in industries such as oil and gas, chemical processing, and power generation. These valves are also known for their durability and reliability, and they are often preferred over other types of valves because of their low cost, ease of operation, and low maintenance requirements.

Detailed parameters

High performance butterfly valve

A. Stem

The high-strength, one piece stem is Stainless Steel. The valve stem is standardized for interchangeability of wesdom actuators.

B. Blow-out Proof Stem

A retaining ring is installed between the machined stem groove and gland retainer step.

C. Adjustable Stem Packing

The stem packing system features easy access to adjusting hex head nuts without requiring removal of the actuator.

D. Stem Seal

The stem seal system provides constant compression for a positive seal around the stem. PTFE packing seals the stem and a carbon fiber anti–extrusion ring contains the packing. Flexible graphite rings are available for high temperature applications and are standard on fire safe valves.

E. Stem Bearings

Top and bottom bearings, consisting of a 316 Stainless Steel shell with a TFE/glass fabric liner bearing surface securely support the stem. The stem bearings provide excellent resistance to corrosion and distortion from high temperatures and mechanical loading forces.

F. Taper Pins

Taper pins are precision fit into reamed holes.

G. Disc

The disc has been engineered to maximize flow and minimize resistance providing a high Cv. Stainless Steel is standard.

H. Internal Travel Stop

Designed to prevent travel of the disc and minimizing possible seat damage, therefore extending the service life of the seat.

I. Resilient Seat

Energizer encapsulated in RTFE

J. Full-faced Seat Retainer

Retainer is firmly attached by bolts located outside of sealing area, protecting the bolts from corrosion.

K. Body

All body styles offer bi-directional sealing as standard to full ASME Class 150, 300 or 600 ratings. Extended neck allows for 2″ of pipeline insulation and easy access to stem packing adjustments and actuator mounting.
