    What Is a High-Pressure Valve?

    A high-pressure valve is an industrial valve designed to meet the crucial requirements of the most demanding applications with performance, reliability, and safety. It is used to allow, obstruct, or control media passage in extremely high pressures and in many cases, high risks and high vibrations. The variations of materials and designs of SIO high-pressure valves guarantee that proper performance is met for any operation.

    SIO high-pressure valves are designed to withstand the most demanding applications, such as extremely high pressures in petroleum industries and cryogenic applications in chemical industries.

    What are the Different Types of High-Pressure Valves?

    Steam Control Valves

    High-pressure Steam Valves

    High pressure steam valves by SIO are widely used in various industries to control pressure and flow levels of hot water vapour, steam, and corrosive fluids. The valve closes to maintain an ideal system pressure when the pressure reaches a certain level.

    Control Valve edited

    High-pressure Control Valves

    These valves are employed to keep the pressure of the operation within the desired range and maintain consistent pressure in a particular part of the equipment.

    The three types of control valves are:


    High-pressure Flow Control Valves

    SIO high-pressure flow control valves regulate the flow and pressure in a specific portion of a hydraulic circuit. It works by responding to the signals made by flow meters and temperature gauges in wastewater treatment, oil and gas, and the power processing plants .


    High-pressure Solenoid Valve

    It is an automatic SIO valve used to control the fluid flow in oil and gas, food and beverage, chemicals and petrochemicals, and cosmetic industries. There are seven types of these valves, each serving a unique actuation mode.

    Double block and bleed valve

    High-pressure Bleed Valve

    A high-pressure bleed valve is used to bleed or vent the system securely for a wide range of applications including, maintenance, equipment removal, and calibrating control devices. It usually works in complex systems with a high pressure ball valve to isolate or block the portion requiring work.

    The three types of control valves are:


    High-pressure Reducing Valves

    High-pressure reducing valves by SIO are perfect for providing a consistent pressure in those parts of the system that work at low pressure compared to the system’s tolerance. It works by matching the gas flow passing through it to maintain a consistent gas pressure.


    High-pressure Safety Valves

    Used for relieving the static pressure in gas applications, chemical plants, and electric power boilers ,high-pressure safety valves by SIO have a manual lever that opens the device during an emergency. This valve works automatically and does not require electricity to operate.


    High-pressure Relief Valves

    SIO high-pressure relief valves are used for curbing the pressure. When the valve opens, the redirected media is routed to a gas flare, releasing the combustion gas products into the atmosphere, limiting the pressure inside the vessel.

    What Valves Can be Used for High-pressure Applications?


    Ball Valve

    A high-pressure ball valve is designed to endure high-operating pressures and manage flows of fluid and other process media. It features a spherical disc with a hollow center that functions as the closing mechanism of the valve.


    Butterfly Valve

    High-performance butterfly valves , which include double offset and triple offset butterfly valves, provide throttling and tight shut-off control for severe conditions, such as high pressures and abrasive, corrosive, and viscous media flow.


    Globe Valve

    High-pressure globe valve is built to start, stop, and regulate media flow that involves harsh service conditions, such as high pressures and toxic materials. It works by turning the stem that allows the disc to go upwards and allow media to go through or downwards to obstruct media flow.


    Gate Valve

    A high-pressure gate valve is an isolating valve designed to fully open or close media passage that involves high pressures and temperatures. It provides tight sealing through a special gasket design and packing made from strong materials, such as pure graphite.

    Pneumatic Diaphragm Valve

    Diaphragm Valve

    A diaphragm valve is a bi-directional valve excellent for managing different types of media flow. It has a flexible disc that comes into contact with the seat found at the top of the valve body to achieve a tight seal.


    Check Valve

    A high-pressure check valve provides leak-proof control of backflow in alternative fuels, instrumentation, and small process applications that need high-pressure flow and cycle life.


    Needle Valve

    A high-pressure needle valve is often used to control flow rates or provide a reliable shutoff of clean fluids and gasses accurately. 、It works by opening and closing an orifice / opening with a tapered end that raises and lowers when spinning a handle.


    Relief Valve

    A high-pressure relief valve is a type of safety valve that prevents overpressure and offers protection to downstream equipment by allowing the pressurized media flow to go through an accessory passage out of the system.

    7 Ways a Solenoid Valve Works

    A direct-acting solenoid valve has a seat seal that attached to the solenoid core. When energized, the solenoid valve will open and when de-energized, the solenoid valve will close.

    A two-way solenoid valve is a shutoff valve that has one inlet port and one outlet port. When energized, the core spring and seal are drawn into the solenoid coil causing the valve to open. When de-energized, the core spring, with support from the fluid pressure, secures the seal on the valve seat to obstruct media flow.

    A three-way solenoid valve is made up of three port connections – cavity port, stop port, and body orifice port and two valve seats – body orifice and stop orifice. In this structure, one seat remains open and the other closed in a de-energized mode. When energized, the valve seats will trade positions. This allows for two paths of media flow.

    When de-energized, the plunger or handle is down which seals the body orifice and opens the stop orifice permitting flow to go through from the cavity port and out the stop port. When energized, the plunger is up which seals the stop orifice and opening the body orifice allowing media to go through it and out the stop port.

    A direct-acting solenoid valve has a static pressure force that increases when the diameter of the orifice increases. This means that the magnetic forces required to endure these pressure forces become significantly larger.

    An internally-piloted solenoid valve is used to switch higher pressures of larger sizes of orifices. In this valve type, the differential fluid pressure does the primary work of opening and closing the valve.

    An internally-piloted two-way solenoid valve is equipped with either a two-way or three-way direct-acting solenoid valve. It has a piston or diaphragm that creates a seal for the main valve seat and an internal pilot to open larger orifices without increasing the size of the solenoid.

    When the valve is closed, the media pressure increases on both sides of the diaphragm through a bleed orifice. As long as there is pressure differential between the inlet port and outlet port, a shutoff force is ready through a larger area on top of the diaphragm. When the valve is open, there is pressure relief from the upper side of the diaphragm.

    An internally-piloted multi-way solenoid valve is made of four port connections – a pressure inlet, one exhaust port connection, and two cylinder port connections. It operates similar to an internally-piloted two-way valve but generally for operating with double-acting cylinders or actuators.

    An externally-piloted solenoid valve uses an external source of air pressure and has an independent pilot device to actuate it. The pilot device is normally mounted at the top of the actuator.
