Valves play a crucial role in the operation of nuclear power plants, serving as the gatekeepers that control the flow of fluids and gases, regulate pressure, and maintain the smooth operation of the entire system. They are akin to the traffic controllers of the plant, ensuring that everything is moving in the right direction and at the right pace.

In essence, valves are essential for maintaining optimal conditions within the plant by regulating the flow of coolant, steam, and other fluids. Any malfunction or failure of valves can lead to significant issues such as disruptions in cooling systems and unexpected pressure spikes, posing a threat to the safety and efficiency of the plant.

At Bhola Engineers, we understand the critical importance of valves in the nuclear industry. That is why we meticulously consider all these factors when designing and manufacturing valves for atomic energy applications. Our dedicated team works tirelessly to ensure that our valves are not only reliable but also safe for use in nuclear power plants, meeting the stringent requirements and standards of the industry.

When it comes to LNG service, it is imperative to select cryogenic ball valves of the double-isolation-bleed (DIB) type 1 or type 2. These valves are specifically designed to meet the demands of cryogenic applications. Liquid nitrogen cryogenic treatment is an integral component of the manufacturing process for cryogenic ball valves. To ensure optimal sealing performance of the packing box and the smooth operation of the ball valves, extended bonnets and drip trays are employed in our designs.

In order to better understand the sealing structure of the valve seat, we at Bhola Engineers analyse the characteristics and sealing principles of both the single piston effect seat and the double piston effect seat. The differing sealing directions can be attributed to the distinct structural characteristics of the seal between the valve seat and the valve body.

The key performance indicator for cryogenic ball valves lies in their sealing performance at low temperatures. To ensure this, we subject our valves to rigorous low temperature simulation tests. Additionally, the type testing of our valves is certified by authoritative organizations, further guaranteeing their reliability and quality.

  • Monoflange Valves

By combining customer-specified valves into a single manifold valve, BEPL’s Mono-Flange significantly reduces the number of potential leak paths. The Mono-Flanges also have a lower system mass, which reduces loading and vibration stresses, further improving safety and reliability. The BEPL Mono-Flange has needle valve primary and secondary rather than ball valves. The Mono-Flange is preferred by some operators as it is smaller than a traditional double block and bleed valve, giving even more space and weight advantages. This ensures that the Mono-Flange is it is a cost efficient option for owner / operators.

The Mono-Flange allows the mounting options to suit whether the pipeline is vertical or horizontal; the gauge or pressure transmitter can be fitted on either the front face or on the outer diameter of the body to allow good orientation and ease of reading.

BEPL’s Mono-Flange is available in a wide range of single-, two- and three-valve configurations, including block, double-block, block-and-bleed, double-block-and-bleed and block-bleed-block. Standard flange sizes include 1/2″, 3/4″, 1”, 1-1/2” and 2”, together with API and DIN standard versions, and there is an extensive choice of flange classes,  from AN S I 1 5 0 to 2 5 0 0 . Standard outlet vents are 1/2″ female NPT.
Depending on Mono-Flange size and configuration, other options include 1/4″, 3/8”, 6 mm, 10 mm and 12 mm sizes, and male NPT or BEPL double ferrule compression fittings.
