High-Performance Butterfly Valves:

Emerson Keystone HiLok and K-Lok

Additionally, we also offer the Emerson Keystone HiLok and K-Lok high-performance butterfly valve models. Each of these models brings its unique features from zero leakage to chemical resistance and high performance in challenging applications. Therefore, they provide a broad spectrum of solutions for different industries.


Size Range

Our butterfly valves typically range in size from 25mm – 400mm (1” – 16”), catering to a wide variety of system requirements.

Temperature Range

The temperature range of our Valves is typically -40°C to 500°C (-40°F to 1000°F). As a result, these valves can handle extreme temperatures with ease.

Pressure Class

Our butterfly valves fall into various pressure classes, including PN6, PN10, PN16, PN40, ANSI 150, and ANSI 300.


Our valves come in Wafer, Semi-lugged, and Lugged connections, offering flexibility based on your system’s needs.

Features & Benefits

One of the key features of our butterfly valves is their zero leakage. This makes them suitable for use with potentially dangerous media and helps to increase efficiency and improve operational safety.

Their good resistance to corrosion and abrasion makes them extremely durable. Moreover, most of our models are available with a choice of seat and seal material options that can be tailored to your requirements.

Another significant benefit of some of our butterfly valves is that they can be repaired. This means you won’t have to replace the entire unit if any issues arise, saving you time and money.

All our butterfly valves can be supplied bare-shaft with a lever/gearbox (size dependant). They are also suitable for actuation either directly or via a mounting kit and drive adaptor.

Suitable Industries

Chemical Industry

Butterfly valves can manage corrosive and non-corrosive fluids. Therefore, they are ideal for chemical processing plants.

Water and Wastewater Treatment

They are widely used in water treatment facilities for their durability and also the ability to handle large flow rates.

Oil and Gas Industry

These valves are suitable for controlling the flow of crude oil, natural gas, and other petroleum products.

Food and Beverage Industry

Due to their sanitary properties, butterfly valves are often used in food and beverage processing plants.

Pharmaceutical Industry

These valves can maintain strict hygiene standards. As a result, they are suitable for pharmaceutical manufacturing.

Power Generation

In power plants, butterfly valves control the flow of steam and cooling water.


They are commonly used in heating, ventilation, and air conditioning systems for flow control.


In conclusion, our butterfly valves at Valve & Process Solutions are designed with your needs in mind. Therefore, whether you need a valve that can handle extreme temperatures or one that offers zero leakage, we have the perfect solution for you.
