Hydraulic Valves

Product Details:

Features:

• Valves are used in Hydraulic systems as very high pressure hydraulic fluid to perform various functions.
• Huge amounts of energy can be transferred over short distances much more efficiently with hydraulic systems than with electrical systems, especially when the desired motion is linear instead of rotational.
• A basic hydraulic system will have a pump, a pressure control valve, one or more control valves, one or more pistons or hydraulic motors that transfer the hydraulic power into motion and a return system that collects the low-pressure hydraulic fluid and feeds it back to the pump for re-use.
• This article focuses on the hydraulic control valve illustrated in below diagram.

Features:

• Check valves are also known as Non Return Valves
• Check valves are self-activating safety valves that permit gases and liquids to flow in only one direction, preventing process flow from reversing.
• They are classified as one-way directional valves.
• Fluid flow in the desired direction opens the valve, while backflow forces the valve closed.
• The mechanics of check valve operation are relatively simple.
• Most check valves contain a ball that sits freely above the seat, which has only one through-hole.
• The ball has a slightly larger diameter than that of the through-hole.
• When the pressure behind the seat exceeds that above the ball, liquid is allowed to flow through the valve; however, once the pressure above the ball exceeds the pressure below the seat, the ball returns to rest in the seat, forming a seal that prevents backflow.
• Check valves use a variety of technologies to allow and stop the flow of liquids and gases.
• Single-disc swing valves are designed with the closure element attached to the top of the cap.
• Double-disc or wafer check-valves consist of two half-circle disks hinged together that fold together upon positive flow and retract to a full-circle to close against reverse flow.
• Lift-check valves feature a guided disc.
• Spring-loaded devices can be mounted vertically or horizontally.
• Silent or center guide valves are similar to lift check valves, with a center guide extending from inlet to outlet ports.
• The valve stopper is spring and bushing actuated to keep the movement "quiet".
• Ball check valves use a free- floating or spring loaded ball resting in a seat ring as the closure element.
• Cone check valves use a free-floating or spring loaded cone resting in the seat ring as the closure element.
• Selecting check valves requires an analysis of performance specifications, materials of construction, connection types, and media.
• Performance specifications include valve size, pressure rating, media temperature, and valve flow coefficient.
• Most check valves are made of acetal polymers, aluminum, brass, bronze, cast iron, chlorinated polyvinyl chloride (CPC), ductile iron, copper, polyethylene (PE), polypropylene (PP), polytetrafluoroethylene (PTFE), polyvinyl chloride (PVC), polyvinylidene fluoride (PVDF), rubber, steel, or stainless steel.
• Connections for check valves can use threads, compression fittings, tube fittings, bolt flanges, clamp flanges, butt welds, socket welds, and union connections.
• In terms of media, check valves are rated for air, compressed air, water, hot water, cold water, potable water, salt water, wastewater, gasoline, diesel fuel, high-purity gas, liquefied petroleum gas (LPG), natural gas, sour gas, corrosive gas, abrasive material, acids, corrosive chemicals, adhesives, concrete, grout, coolants, hazardous materials, high-viscosity fluids, hydraulic fluids, liquid metal, lubricants, oil, powders, solids, rendering wastes, sludge, slurry, ash slurry, or steam.
• Check valves are available in Steel, Stainless Steel, Brass Materials & can be applicable for Low pressure Application, High pressure Application & for water.

Features:

• Ball valves are quarter-turn, straight through flow valves that have a round closure element with matching rounded seats that permit uniform sealing stress.
• Ball valves are used in situations where tight shut-off is required.
• The type of seat can vary with the valve pressure rating and materials of construction.
• Ball valves seats are composed of single molded forms, while other seats with higher-pressure ratings often incorporate a trunnion design where each face of the ball is separately sealed.
• Ball valves are wide duty valves, able to transfer gases, liquids and liquids with suspended solids (slurries).
• Ball valves offer many advantages when contrasted with other valve types.
• Ball Valves can provide superior ease of operation and can maintain and regulate high volume, high pressure and high temperature flow.
• Ball valves offer rugged construction providing for a long service life, and a comparably low cost.
• Additionally, the design of the regulating element allows the valve to function without the complications of side loads, typical of butterfly or globe valves, and the valve design permits inspection and repair of seats and seals without removing the valves' body from the line.
• Ball valves are available in a variety of body styles, including one-piece, two-piece, three-piece and flanged body construction.
• Ball valve forms offers specific advantages depending upon the requirements of the given application.
• Ball Valves are designed using a wide variety of materials, as required by their application.
• Ball valve materials include brass, bronze, copper, cast iron, ductile iron, stainless and other steel types, metal alloys and plastics including PVC and CPVC.
• It is best to consult with the manufacturer for the specific properties of the materials used in the valve, and how this relates to the applications that include type, concentration and temperature of the media being handled.

Product Details:

Features:

• Needle valves have a slender, tapered point at the end of the valve stem that is lowered through the seat to restrict or block flow.
• Fluid flowing through the Needle valve turns 90 degrees and passes through an orifice that is the seat for a rod with a cone shaped tip.
• Needle valves are widely used to accurately regulate the flow of liquids and gases at low flow rates.
• The fine threading of the stem and the large seat area allow for precise resistance to flow.
• Needle valves are used to control flow into delicate gauges,which might be damaged by sudden surges of fluid under pressure.
• Needle valves are also used in situations where the flow must be gradually brought to a halt, and at other points where precise adjustments of flow are necessary or where a small flow rate is desired.
• Needle valves can be used as both on/off valves and for throttling service.
• Needle valves are often designed with a metal needle (generally brass, bronze, or stainless or other alloys of steel) and an elastomeric seat (generally PVC, CPVC, PTFE, or a wide range of brand name plastics and thermoplastics).
• While this is the most common form, valves are available that have metal - metal, plastic - plastic, or plastic- metal needles and seats.
• These variations are usually designed with specific applications in mind, especially situations where corrosion, high or low temperatures or extensive wear are possible.
• In such cases, it is best to consult with the manufacturer to find which type of valve is best for the application at hand.
• Needle valves are used in almost every industry in an incredibly wide range of applications - anywhere control or metering of steam, air, gas, oil, water or other non-viscous liquids is required.
• Needle valves can be found in every industry from aerospace to zoological sciences, every service from gas and liquid dispensation to instrumentation control and cooling to power generation.
• However, Needle valves should be avoided in applications where the media is viscous, or in the dispensation of slurries.
• The small flow orifice can easily trap thick materials or solids and become blocked.
