Our team at Virgin engineers joined decades of experience as research to build up a line of products that are insightful creative and offer most outrageous utility. We have supplied, and traded Stainless Steel 316H Needle & Gauge Valves to our domestic and international customers. We produce different types of valves under the norms of international standards, customers can avail them in various standards, designations, specifications, and non-standard dimensions.
Stainless Steel 316H Needle & Gauge Valves description:
Needle & Gauge Valves are fittings developed with a tapered and slender point at the end of its valve stem. The valve stems which is actually lowered right via the seat to restrict and start the flow. These valves are used to ensure that the fluid passes via the valve and actually turns 90 deg before it passes through an orifice which serves as the seat.
The seat of valves comes with a rod having a cone shaped tip. These valves are actually used to regulate the flow gases and liquids which are set at low flow. It has the fine threading design of the needle valve stem; along with due to its large seat area ensure that precise resistance will follow. SS needle and gauge valves are used to control and check the flow of liquid and gasses into the dedicate systems, thus a higher risk of suffering damages have occurred if subjected to extreme pressures.
These valves are also utilized in heavy industrial equipment, even the flow needs to bring to a final halt. Mainly, these valves are utilized where a precise adjustment of the flow is considered essential, or where the small and controlled flow is required. These valves can readily be used as both off and on valves, along with use in a system for throttling working.
These types of fittings are used to control and decrease the flow of air in the leg of the pneumatic system, results in slowing down the actuator set. The basic function of both fittings are is flow restriction, even the main difference is needle valve controls the flow of gas or liquid, while the flow control valve only ensure the control in one direction only.
The Steel 316H Needle & Gauge Valves are bi-directional, while the flow is one-directional only. In the fittings, there is a fine thread stem allows the gradual adjustment of the quantity of controlled flow that passes through the valve. The controlled flow enters the input and output slots through the orifice, which is actually sized by the tapered stem and through the output port. The flow of fittings features a simple bypass feature that allows tending a rapid and free flow, out from the output port, by means of the inlet.
We conduct different types of testing on a manufactured range of valves for assured quality. Before a SS 316H Needle & Gauge Valves are chosen for systems, it is essential that customers assess the flow rate requirements of pneumatic systems.
