Steam Valves

Steam Valves

Our company doesn’t only supply hydraulic and pneumatic valves in Glasgow, we also supply many other valves and products including steam valves. We can provide steam valves in many different materials such as aluminum, brass, bronze, cast iron, ductile iron, copper, steel, or stainless steel.

Types of Steam Valves

Angle valves position the inlet and outlet at 90º to provide maximum flow.

Ball valves offer tight shutoff, predictable control, and ease of operation.

Bellows valves feature a contaminant free, positive shutoff for high-purity gas and fluid systems.

Butterfly valves control flow through a circular disc or vane by turning the valve’s pivot axis at right angles to the direction of flow in the pipe.

Cartridge valves are directional control valves which are inserted into manifolds.

Check valves are self-activating safety valves that prevent process flow from reversing.

Diaphragm valves use an elastomeric diaphragm to separate the flow stream from the closure element.

Gate valves or knife valves use a flat closure element to provide shutoff.

Both pinch valves and globe valves provide on/off control and throttling service.

Plug valves or stop-cock valves raise or lower a cylindrical plug within a seat to control flow.

Poppet valves open and close ports with a sealing device composed of a disk, cone or sphere that is pressed against the seating surface using a spring.

Other types of steam valves include regulators, servo valves, solenoid valves, spool valves, and toggle valves.

Specifications for Steam Valves

Specifications for steam valves include

valve size – valve size represents the size of the passage opening

pressure rating – pressure rating is the maximum pressure, usually measured in pounds per square inch (psi), for which products are rated

number of ports or ways

valve flow coefficient – valve flow coefficient is the number of gallons per minute of at which 60º F water flows through a valve at a specified opening with a pressure drop of 1 psi across the valve

connection type

Connection Type

There are many different connection types for steam valves. Threaded valves have internal or external threads for inlet or outlet connections. Compression fittings do not require soldering or threading because tightening the nut on one fitting compresses a washer to form a watertight closure. Some steam valves have bolt flanges, clamp flanges, union connections, or tube fittings. Others have socket weld or butt weld connections. Valves with a metal face seal sandwich a metal gasket between two fitting parts.
