• Flowchem industries, a leading provider of flow control products and services for the global infrastructure markets, has announced the launch of the double scotch yoke actuator ("cp" & "cy") series.
• The "cp" series is for heavy duty and high torque application & "cy" is targeted for smaller size valves. The "cp" & "cy" is ideal where pneumatic motive power is preferred and for services requiring robust design, long service life, high-torque and high-speed operation. It is suitable for on/off, modulating and control applications of quarter-turn valves, offshore environment as well as in general, protective and safety services such as emergency shutdown (esd) or high-integrity pressure protection systems (hipps), up to and including "sil" 3 level in accordance with iec 61508.
• Our actuators are designed to meet or exceed the most current and stringent safety and reliability standards for oil and gas services; it is the modular, pneumatic driven piston-type, scotch yoke actuator. Its maintenance interval is up to six years or as prescribed in en 15714 for high-cycle applications and an industry leading, 25 year design life, depending on service conditions, proper installation, operation and maintenance.
• The ruggedly built "cp"/"cy" series actuators delivers up to 63 knm and a maximum allowable working pressure (mawp) of 12 bar (g), with minimal wear and maximum efficiency. The "cp"/"cy" series actuators is available in single acting spring return or double acting configurations for operation in a wide range of standard, low and high temperature environments from -29 c (-20 f) for spring return units and -60 c (-76 f) for double-acting units up to 160 c (320 f). It has been designed and manufactured in accordance with: ip66/ip66m and ip67/ip67m per en60529 and en 15714-3. It also meets global standards and approvals like ce marking as per atex 2014/34/eu;ped 2014/68/eu, md 2006/42/ec directives and "sil" capable to level 3 as per iec 61508.
• The "cy" series will cover ball valve, butterfly valve and plug valve up to 2000nm torque and "cp" series will cover valves up to 40000nm torque.

Features

• A Globe Valve is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a body. Globe valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle. This has an opening that forms a seat onto which a movable plug can be screwed in to close or shut the valve. The plug is also called a disc. The plug is connected to a stem which is operated by screw action using a hand wheel in manual valves.

Features

• A Non-Return Valve or Check valves are one-way valve normally allows fluid (liquid or gas) to flow through it in only one direction. Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications. Check valves are often part of common household items. Although they are available in a wide range of sizes and costs, check valves generally are very small, simple, or inexpensive. Check valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem.
• An important concept in check valves is the cracking pressure which is the minimum upstream pressure at which the valve will operate. Typically the check valve is designed for and can therefore be specified for a specific cracking pressure.
• A Lift-Check Valve is a check valve in which the disc, sometimes called a lift, can be lifted up off its seat by higher pressure of inlet or upstream fluid to allow flow to the outlet or downstream side. A guide keeps motion of the disc on a vertical line, so the valve can later reseat properly. When the pressure is no longer higher, gravity or higher downstream pressure will cause the disc to lower onto its seat, shutting the valve to stop reverse flow.

• A Swing Check Valve is a check valve in which the disc, the movable part to block the flow, swings on hinge either onto the seat to block reverse flow or off the seat to allow forward flow. The seat opening cross-section may be perpendicular to the centerline between the two ports or at an angle. Although check valves can come in various sizes, large check valves are often swing check valves.

Features

• Three - and four - way have an L- or T-shaped hole through the middle. The different combinations of flow are available. It is easy to see that a "T" valve can connect any pair of ports, or all three, together, but the 45 degree position which might disconnect all three leaves no margin for error. The "L" valve can connect the center port to either side port, or disconnect all three, but it cannot connect the side ports together.
• Multi-Port Ball Valves with 4 ways, or more, are also commercially available, the inlet way often being orthogonal to the plane of the outlets. For special applications, such as driving air-powered motors from forward to reverse, the operation is performed by rotating a single lever four-way valve. The 4-way ball valve has two "L"-shaped ports in the ball that do not interconnect, sometimes referred as "X" port.

Specification

Features

• A Ball Valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle. The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve's status
• Ball Valves are durable, performing well after many cycles, and reliable, closing securely even after long periods of disuse. These qualities make them an excellent choice for shutoff and control applications, where they are often preferred to Gate and Globe Valves, but they lack their fine control in throttling applications.
• A Trunnion Ball Valve has additional mechanical anchoring of the ball at the top and the bottom, suitable for larger and higher pressure valves.
• Double Block and Bleed feature for TMBV
• Fire Safe Design
• Blowout proof Stem
• Antistatic Feature
• Mirror finished Ball

• A Floating Ball Valve is one where the ball is not held in place by a trunnion. In normal operation, this will cause the ball to float downstream slightly. This causes the seating mechanism to compress under the ball pressing against it. Furthermore, in some types, in the event of some force causing the seat mechanism to dissipate (such as extreme heat from fire outside the valve), the ball will float all the way to metal body which is designed to seal against the ball providing a somewhat failsafe design.
