Class 150 (AKA 150#) refers to the pressure/temperature rating of the valve. That class applies to steel and alloy steel valves. Common classes are 150, 300, 600, 900, 1500, 2500, 4500. There are also interpolated ratings and special classes, which basically are intermediate ratings. For more information click the Related Link shown below.

Gate valve manufacturer in India?

Specialityvalve is one of the biggest producer and supplier of Gate valve Manufacturer in India. Gate Valve is a control valve that either allows the fluid flow or stops it depending upon our use. It is a most common valve for water valve systems. It is a linear motion valve that starts or stops the flow. It got its name from the element sliding into the flow stream to provide shutoff, hence acting like a gate. Thus it is used either in the fully closed or fully open positions. Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid. When the gate is fully opened it enables the gate valve to offer straightway flow with very little pressure drop. Gate Valves are also called as Sluice Gate Valve. Automated Gate Valve also exists which are either electric or pneumatic actuator, but as manual gate valve are cost effective hence it is affordable and as gate valves are used lesser. Gate valves should not be used for regulation or throttling of flow because accurate control is not possible. Components of Gate Valve ● Body ● Bonnet ● Body Seat ● Stem Nut ● Yoke Nut ● Stem ● Handwheel ● Gasket Working of Gate Valve The main three components of Gate Valve are: body, bonnet and stem When the handwheel is rotated which rotates the stem and due to it there is vertical movement of the gate via threads. They are considered multi-turn valve as it requires more than 360 degree to fully open the gate. When the gate is lifted from the flow path, it is open and when it returns it is closed and hence the flow is stopped. Types Knife Gate Valve Wedge Gate Valve Parallel Slide Gate Valve Slab Gate Valves Pressure Seal Gate Valve Flat Gate Valve Below Seal Gate Valve Forged Gate Valve Advantages • Have low friction • They provide laminar flow • They help to reduce energy and low cost of ownership • There is small flow resistance • Structure length is relatively short Industries ● Oil and Gas ● Automotive ● Marine ● Chemical ● Petrochemical Description Available materials: SS304, SS904, SS904L, SS316, Aluminium Bronze, Monel, Bronze, Brass, Duplex steel, Inconel, Titanium, WCB, CF8, CF8M, CF3, CF3M, WC1, WC6, WC9, Cast iron, SPUER DUPLEX Size: 1/2″- 64” Class: 150 to 2500 Nominal Pressure: PN10 to PN450 Operations: Hand Wheel operated Gate valve, Gear operated Gate valve, Electric actuated Gate valve and Pneumatic Actuated Gate valve Ends: Flanged(FF,RF,RTJ), Buttweld, Socket weld, Threaded Standards: API607, DIN, BS, ANSI, AWWA, ASME, API6D With an experienced technical team, Specialityvalve provides best Gate Valve Manufacturer in India.

What valve is the preferred valve to use in throttling a gate valve or globe valve?

Never ever use a Gate type of valve for throttling ONLY a globe pattern is designed for this purpose and a needle valve


What type of valve is used in a peanut butter factory ball or gate or globe or gate?

gate valve. globes are used for throttling and have far too many turns. ball valves are not made for thick stuff. this question was on the inter-provincal exam they had globe valve, gate valve, diaphragm valve and piston valve. for answers too choose from.


What is difference between ANSI b 16.5 class 150 and ANSI b 16.5 class 1500?

The Class ranges of ANSI Standards refers to the pressure and temperature limits of usage for the Product. The class ranges from 150 and goes upto 2500. They denote the different pressure ranges. For example, A 316 Stainless Steel valve in class 150 can be used only upto 275psi Same 316 Stainless Steel valve in class 1500 can be used only upto 3600psi Does that clears your doubt?
