Plug Cocks & Plug Valves FAQ

Below you'll find answers to the most common questions about our plug cocks and plug valves collection. If you need further guidance, our technical team is always happy to help you find the right valve for your application.

What is the difference between a plug cock and a plug valve?

Both use a tapered or cylindrical plug to control flow, but the terms are often used interchangeably depending on the manufacturer and size range. Generally, "plug cock" refers to smaller, simpler quarter-turn devices used for isolation or sampling, while "plug valve" tends to describe larger, more robust units rated for higher pressures and more demanding service conditions. If you're unsure which suits your application, get in touch and we'll point you in the right direction.

What types of plug valves do you stock?

Our collection includes lubricated and non-lubricated plug valves, sleeved plug valves, and traditional plug cocks in a range of sizes and materials. We carry products from trusted manufacturers to cover applications across water, gas, steam, oil, and chemical processing. If you can't find a specific variant on our site, contact us as we can often source it.

What materials are your plug valves available in?

We supply plug valves in materials including brass, cast iron, ductile iron, carbon steel, and stainless steel. The right choice depends on your media, operating temperature, and pressure requirements. Our team can advise on material compatibility if you're working with corrosive or specialist fluids.

What pressure ratings and sizes do you offer?

Our plug valves and plug cocks are available across a range of sizes and pressure classes to suit most industrial pipework systems. Specific ratings vary by product and manufacturer, so check individual product listings for detailed specifications. If you need a particular rating or size that isn't listed, contact us and we'll do our best to source it.

Are your plug valves suitable for gas applications?

Yes, many of our plug valves are approved for use with natural gas and LPG. Always check the individual product specification to confirm suitability for your gas type, pressure, and installation requirements. We can help you identify the correct valve if you provide your application details.

How do I choose the right plug valve for my application?

Start by identifying the media (water, gas, oil, chemicals), the operating pressure and temperature, the pipe size, and the connection type you need. From there, material compatibility and any relevant industry standards will narrow your options. If you'd prefer expert guidance, call or email our technical team with your requirements and we'll recommend the best solution.

Can I order plug valves in bulk for a project?
