Why Choose Us

As part of your procurement process, you may be assessing more than one supplier of valves. Naturally, we hope you choose BFV Valves. To help you arrive at that decision, here are 10 key reasons why so many blue-chip brands, consultants and engineers buy their valves from us.

  • We’re a “safe pair of hands”. With decades of experience between us, we are one of the China’s leading valve supply specialists.
  • Our price strategy is to deliver exceptional value – without exception. We don’t supply cheap inferior valves with parts that will wear out prematurely. We supply superb quality, safe and durable valves with an outstanding technical and consultancy service, backup and spare parts.
  • Because of our experience and considerable buying power our customers benefit from competitively priced valves, each one quality checked and certified to internationally recognised standards.
  • We offer a high-value consultancy service with free no obligation on-site surveys.
  • Our suppliers are handpicked from the very best worldwide manufacturers with quality of the upmost importance, audited by our agents and ISO 9001 accredited.
  • A director will always be responsible for looking after your order. It’s our goal to make your ordering experience easy, smooth and uncomplicated. So you can ask for a quote on the telephone (which we’ll follow up in writing) and you don’t need to quote parts’ numbers. Our aim is to assess your needs as quickly and efficiently as possible in order to quote you promptly.
  • We’ll always provide you with a realistic and achievable delivery time. Some suppliers will offer unrealistic delivery times despite your valves being on a longer lead time simply to get your business. We’ll give you an accurate delivery time and will track your order from initial confirmation through to delivery.
  • We’ve built a reputation for being a fair and ethical business. So we won’t sell direct to your customer and try very hard to avoid this at all costs.
  • Within our warehouse at our manufacturing unit in Kent, we have a purpose built test zone. Customers value this when goods are being shipped overseas. We can certify their valves have been tested to the required standard and are in perfect working order when they leave us. We do not charge for this service. We can also provide a storage and distribution service within our warehouse, again usually at no charge. And of course special packaging and tagging.
  • Crucially, we will recommend the correct valves to you. This is a direct result of our experience and expertise and simply by asking the right questions about how your valve will be used. We’ll ascertain any risk of explosion and if required will recommend explosion proof ancillaries. It is vital to us that the valves you receive meet your requirements to the letter and that they’re safe.

Knife Gate Valve

Knife gate valve is a type of valve that is specifically designed to control the flow of fluids in a pipeline. It is commonly used in industries such as mining, wastewater treatment, and pulp and paper, where solid materials can be present in the fluid being transported. The unique design of the knife gate valve allows for a tight shut-off, making it ideal for applications where leakage cannot be tolerated.
The knife gate valve gets its name from the sharp-edged gate that is used to control the flow of the fluid. This gate is typically made from stainless steel or another durable material that can withstand the harsh conditions often found in industrial settings. When the valve is in the closed position, the gate is pressed against a resilient seat, creating a tight seal that prevents any fluid from leaking through.
One of the key advantages of a knife gate valve is its ability to handle high-density slurries and solid materials that can cause problems for other types of valves. The sharp edge of the gate cuts through any solids present in the fluid, allowing for a smooth and efficient flow. This makes the knife gate valve a popular choice for industries where the presence of solids is common.
In addition to its ability to handle solid materials, the knife gate valve is also known for its ease of maintenance. The simple design of the valve means that it can be easily disassembled for cleaning or repairs, reducing downtime and increasing efficiency in industrial operations.
Overall, the knife gate valve is a versatile and reliable tool for controlling the flow of fluids in a wide range of industrial applications. Its ability to handle solid materials, tight shut-off capabilities, and ease of maintenance make it a popular choice for industries where efficiency and reliability are key priorities.

Knife Gate Valve

Knife gate valve is a type of valve that uses a sharp-edged disc to cut through and seal against the flow of liquid or gas. It is commonly used in industries such as mining, wastewater treatment, and pulp and paper production. The knife gate valve is known for its ability to handle thick, viscous fluids and slurries, making it a popular choice for applications where traditional gate valves may not be suitable. The design of the knife gate valve allows for easy maintenance and replacement of the sealing disc, ensuring long-lasting performance and reliability.
