How Do Swing Check Valves Work?
Swing check valves contain a gate which swings away to allow flow in one direction.
When the flow is stopped, the disc will swing back onto the seat, automatically closing the valve as the pressure decreases. Swing check valves allow for full flow as the gate opens fully when under pressure.
The top inspection cap allows for easy servicing and cleaning of the gate. Our swing check valves have a stainless steel body and disc and have a maximum pressure of 230 PSI.
They also have a temperature rating from -20 degrees celsius to 180 degrees celsius. Swing check valves have parallel female BSP threaded ends. We stock swing check valves from ½ inch right up to 4 inch.

How Do Spring Check Valves Work?
Spring check valves allow fluid to flow in one direction.
The force of the flow will allow the gate in the valve stopper to open to allow the desired flow. Our range of spring check valves have a stainless body and disc with parallel female BSP threaded ends.
We stock spring check valves in 2pc and 3pc. We have 2pc spring check valves from ⅜ inch right up to 2 inch and for the 3 pc spring check valves, from ½ inch right up to 4 inch. These spring check valves are vertical valves and are not suitable to be installed in an horizontal position.
The temperature rating of these valves are from -20 degrees celsius to 180 degrees celsius. Spring check valves have a maximum pressure rating of 580 PSI.

Sampling Valves
Sampling valves are a type of valve which is used for taking small samples of liquid from tanks or pipelines.
This is typically done for purposes such as quality control, identification and regulatory assessment. The valves are used in a variety of industries such as food and beverage, pharmaceutical, cosmetics and chemical. They are also used in laboratories and research facilities.
Our sampling valves have silicon seals. The advantage of using silicon is that it is inert and does not react with any chemicals in the sample.

Y Strainers
Y strainers are named for their Y-shaped body, which houses a sieve-like mesh filter that is placed in the path of the fluid flow.
Y strainers are named for their Y-shaped body, which houses a sieve-like mesh filter that is placed in the path of the fluid flow. As the fluid flows through the strainer, the foreign matter is caught on the screen and is prevented from continuing down the pipeline. The Metal Company stock two types of Y-strainers to suit different sizes – BSP Threaded Stainless Steel Y strainers from ½” up to 2”, and Ductile iron Y strainers from 1 ½” up to 8”. The small BSP Threaded Y strainers have a fully stainless body and filter and parallel female BSP Threaded ends.
Ductile Iron Y strainers have a fusion bonded epoxy coating on the body and use a stainless steel mesh. They also include a drain plug in the cap, as well as table E flanged ends. Both of the valves have a removable cap so the strainer can be removed or cleaned. Y strainers are easy to install and maintain, and they are an economical option for protecting your pipeline from damage.

Sanitary Ball Valves
Sanitary ball valves are a ball valve especially designed for use in a sanitary or hygienic process lines.
The valves feature a full-bore design that enables full fluid flow with minimal pressure drop. This makes them ideal for handling viscous liquids or liquids containing particles in the food, beverage, chemical and pharmaceutical industries. A sanitary ball valve has a few key components that make it different from a standard ball valve. The first is the body. The body of a sanitary ball valve is made from stainless steel and is polished to a high shine to ensure it is smooth and easy to clean. The second key component is the ball. The ball in a sanitary ball valve is also made from stainless steel and polished to a high shine. The third key component is the seal, which is made from EPDM to ensure a tight seal. This also means the maximum working temperature of the valve is 120 degrees Celsius. The fourth and final key component is the handle. This is a pull and twist, multi position handle so the ball valve can be used to control flow.

Sanitary Non-Return Valves
Sanitary non-return valves allow for flow to move in one direction and are able to stop fluid from returning through the valve in the opposite direction.
The valve contains a gate which closes off the flow. When pressure is applied the gate will open in the direction of the flow. We stock these valves that butt weld to imperial tube, tri clover connections, or RJT connections. These valves have a tri clover clamp around the centre. That means you can easily open these valves for cleaning and inspection. We also stock seal kits for these valves.

What Are Piston Check Valves?
Piston check valves are a type of valve that allows fluid to flow in one direction. Rather than a spring, these valves consist of a cylinder and piston. This piston has a PTFE seat which causes a tight seal. These valves also have an inspection cap where the piston can be serviced or removed while in place. These valves have parallel female BSP threaded ends and have a maximum pressure of 800 PSI. They are suitable for use up to maximum working temperature of 230 degrees celsius. We stock these valves from ½ inch right up to 2 inch.

What Are Needle Valves?
Needle valves are used to regulate small amounts of flow or high pressures through either an appliance or system.
The unique feature about these valves is that they have a small plunger which is similar to a needle, hence the name needle valve. The needle valve’s needle fits into the seat of the valve. Due to this, needle valves are able to accurately control fluid flow through the valve.
These valves have parallel female BSP threaded ends, contain a PTFE seal and are controlled using a T handle.
The maximum temperature rating of these valves is 200 degrees celsius and the maximum pressure this valve can handle is 6000PSI. We stock needle valves in 1/4 and ½ inch.

What Are Ball Valves?
Ball valves are classified as a quarter turn shut-off valve which controls the flow of fluid or gas with its rotating ball. These valves are known as a full port valve as the spherical ball has a straight bore right through it meaning that the flow path has no restriction of flow. This is because it is equal to the inside diameter of the pipe or tube that it is mounted to.
The valve can be opened or closed by turning the lever on the top of the valve. For the flow to pass, the bore should be aligned with the flow of the fluid. To block the flow, the ball can be rotated perpendicular to the flow path.
These valves are very versatile as they can be used in a wide range of applications as they can withstand high temperatures and pressures, easy to use and inexpensive.

Types Of Cast Iron Butterfly Valves
Wafer Type Butterfly Valve
The Wafer type Butterfly Valve is placed between pipe flanges, and the flange bolts surround the valve body. The Wafer Type Butterfly Valve is suitable for most flanges (including Table E, PN16 and Ansi150). If either side of the valve needs maintenance, then the entire line must be shut down
Lugged Butterfly Valve:
The Lugged Butterfly Valve has threaded lugs on the periphery of the valve body to provide passages for bolt holes that match with those in the flanges. This design enables the disconnection of one side of the line without affecting the other. The Butterfly Valve is classified as a quarter-turn valve. This works like a ball valve for quick shutoff, however, it can open and close incrementally unlike a ball valve.
