An instrument needle valve uses a tapered pin to gradually open a space for fine control of flow. The flow can be controlled and regulated with the use of a spindle. A needle valve has a relatively small orifice with a long, tapered seat, and a needle-shaped plunger on the end of a screw, which exactly fits the seat. These needle valves are an ideal option for isolating or throttling applications. The self centering, non rotating stem ensures perfect seating. The rigid design gives repetitive bubble tight shut off, easy.

With rich expertise, we are offering a wide range of Needle Valves that is generally used in flow metering applications, especially when a constant, calibrated, low flow rate must be maintained for some time, such as the idle fuel flow in a carburetor. Our needle valves are appreciated in the market for low operating torque and high tensile strength. Further, these are provided in proper packaging to the clients in order to prevent wear and tear during transportation. Needle Valves or Shut-Off Valves are designed to Isolate, Calibrate and Drain Process Lines by Line Mounting.

Forged Globe Valves Threaded components have led the way for over past years in state- of-the-art design and dependable performance. It is qualities like these, combined with a customer-driven culture, that maintains Bonney Forge's leadership position within the industry for exceeding customer expectations. .

Globe valves consist of a movable disk-type element and a stationary ring seat in a generally spherical body. The valve stem moves a globe plug relative to the valve seat. The globe plug can be at any position between fully opened and fully closed to control flow through the valve. The globe and seat construction gives the valve good flow regulation characteristics. Turbulent flow past the seat and plug, when the valve is open, results in a relatively high pressure drop, limited flow capacity, and low recovery.

Forged Gate Valves are primarily designed for on-off services when a straight-line flow of fluid and minimum restriction is desired. The closure member of gate valves either stops or allows flow through the valve and acts somewhat like the opening or closing of a gate and is called, appropriately, the gate valve. The gate is also shown as a wedge, due to the shape is resembles. When the valve is open, the closure member is fully drawn up into the valve, leaving a complete opening for the flow stream. Therefore, there is little pressure drop or flow restriction through the valve. Gate valves are used in many industrial applications including the oil and gas industry, pharmaceuticals, manufacturing, automotive, and marine. Gate valves are not suitable for throttling purposes.

These valves are widely used in Refineries and Petrochemical Industries, Fertilizer Plant, Thermal Power Plant and other process industries. With socket and screwed end connection, these valves are designed for handling very high pressures. Its rigid and sturdy design along with low pressure across the valve make it a very formidable model in the entire product line.

Single block and bleed valves are used to achieve positive isolation when performing maintenance activities in a live process plant. Typically one block valve and a bleed valve are manufactured as a single assembly and this single block and bleed valve manifold can be readily installed for isolation purpose. There is a lot of misunderstanding surrounding the term ingle Block Valve-MB1 Series as used to describe valve functionality. It seems almost every valve buyer and manufacturer has a different idea of what the term means for valve selection, which can result in the wrong specifications or valve type. Some of this confusion in the oil and gas industry stems from the fact that there are two credible sources that define the term differently. .

Single block and bleed valves are usually used for non-critical process service, such as low pressure system or non toxic, non hydrocarbon, non-hazardous process fluids. For critical service, double block and bleed valve assemblies must be used. To perform positive isolation while performing maintenance, repair or shutdown activities, single block and bleed can be used in the following way. The block valve is closed first. The shutdown side of the block and bleed assembly is then drained/vented/purged to make ready for maintenance.
