KINGSTON VALVES

Founded in 1908, Kingston Valves manufactures and supplies heavy-duty industrial valves. These valves are ideal for process control equipment, steam-fired autoclave sterilisers, hyperbaric therapy chambers and fire repression systems. Read More

About Kingston Valves

The company's extensive catalogue includes a wide range of relief, safety, check, condensate drain and ball valves. Kingston ball valves feature a simple quarter-turn handle to control the opening / closing operation of the chrome-plated brass ball. The brand's KBV Series ball valves feature a full-port design and are compatible with air, water, oil and inert gas services. The brand also offers a pressure regulator that is designed to hold the pressure range (10 - 150 psig) regardless of flow variation and features a neoprene diaphragm that offers resistance to oil, air, moisture as well as wear & tear of internal components.

Things to Consider

Cross-Reference Alternatives

Kingston Valves MPNs cross individual references to the equivalent Conrader and Parker pneumatic control and automatic drain valves. So, if you're looking for a competitor item that is either out of stock or obsolete, chances are Raptor Supplies has the equivalent Kingston Valves products available.

Shipping

These Kingston Valves products range from small to large sizes. They may require careful packaging as some items might get damaged while shipping. Hence, these Kingston Valves items are delivered by courier shipment and air freight for minimum downtime.

Kingston Valves Competitive Advantages

HCR Diaphragm

This patented diaphragm is composed of EPDM with dual layers of chlorine and chloramine-resistant elastomer, designed to outlast the harshest of chemicals typically found in recycled water systems. This two-piece diaphragm comes with a Superior Shield assembly that helps to deflect debris to prevent diaphragm tears.

Frequently Asked Questions

What mounting orientation should be used to install a Kingston relief valve?

Kingston safety relief valves must be installed vertically with the drain holes opened to a convenient location for safe discharge. Installing a valve in any other position will adversely affect the performance and service life of valve components.

What is the purpose of using a soft seat safety valve?

A soft seat safety valve utilises an elastomer, such as Silicone, FKM (Viton), EPDM (Teflon), Nitrile (Buna-N) or PTFE for sealing the internals of the valve depending on the compatibility of media flowing through it.

How high should the system pressure be before the valve opens?

Always maintain a minimum operating gap of 10 percent between the system operating pressure and the safety valve's nameplate set pressure.

What is the function of a drain hole in Kingston valves?

The drain hole is required in some models to prevent condensate from accumulating in the valve body which may freeze or corrode internal parts and prevent the valve from opening.

What is water hammering?

When high-speed water is forced to change direction or stopped abruptly, it causes a 'bounce-back', commonly known as water hammering. Such sudden stoppages of flow can increase the pressure from the shock waves and can cause significant damage to the overall piping system. This can be prevented by using spring-assisted check valves that silently move the valve into a closed position before flow reversal takes place, thus reducing the possibility of a water hammer.
