Doering Co. has redesigned its manual cartridge valve to include extremely low- and zero-leak options. The company’s zero-leak technology is integrated in the Doering valve used for manual fire suppression in the International Space Station and was specifically engineered to hold pressure for 15 years. The demand for Doering’s redesigned manual cartridge valves has grown […]
Are hydraulic sequence valves dead?
By Josh Cosford A sequence valve is a pressure valve designed to open when its set pressure is reached, providing a path of flow alternate and sequential to the primary circuit. In some ways, a sequence valve is a directional valve, allowing flow to occur. However, it’s just a relief valve with some added features. […]
Canfield Connector launches hydraulic valve connector
The new series 5K DIN valve connector from Canfield Connector is compatible, versatile and dependable and enhances two of its product lines. An innovator in the manufacturing of electronic devices, Canfield Connector offers the 5K connector without the integrated gasket design to promote version compatibility with the company’s MCCR (Multiple Control Connector Receptacle) and its […]
Efficient slip-in check valves support axial, 90° flow paths
Inserta Products introduces its IGS (Steel) Check Valves, Guided Disc, Slip-In Type for use in both axial and 90° flow path configurations. The guided disc provides increased longevity in adverse flow conditions such as turbulent flow with the valve partially open or with high flow transients on valve opening and closing. These valves have low […]
Sectional mobile valves with integrated electrohydraulic control
Among all hydraulic directional-control valves used in mobile equipment applications, the spool valve is arguably the most popular, and sectional types allow for flexible construction. The VD8A directional-control valve from Salami SpA, Modena, Italy, has a modular construction and consists of an inlet section, up to eight working modules and an outlet section. All the […]
Bucher flow dividers offer higher precision
With a deviation of just 1.5%, new flow dividers from Bucher Hydraulics, Klettgau, Germany, offer higher precision compared to their more-conventional counterparts. The new versions complement an extensive product family of the company’s MT series of flow dividers. These automatically operating units split a volume flow into two part-flows that can vary within certain limits. […]
Hydraulic valves for explosive atmospheres
Potentially explosive mixtures of gas, vapor, mist or dust aren’t unusual in many chemical and petrochemical plants or, for example, in mines. Thus, it is necessary to ensure a high level of protection against explosion for every component on equipment used in these industries, according to officials at ARGO-HYTOS, Zug, Switzerland. When using hydraulic components, […]
Sun Hydraulics launches Sun FLeX Series solenoid valves, coils
Sun Hydraulics Corp. has announced the availability of 16 completely new solenoid-operated cartridge valves and three new coils for the mobile and industrial hydraulics marketplace. These newly designed valves—including on/off and proportional models—are the first phase of products introduced in the Sun FLeX Series Solenoid Valves. Coil options for the family include interchangeable low-power, high-power […]
DMIC expands BVH Series of ball valves
Delaware Manufacturing Industries Corp. (DMIC) is pleased to announce the expanded BVH series of high pressure, high quality ball valves. These precision valves are engineered and manufactured in the USA to provide faithful service in demanding fluid handling applications to 7,500 psi. The BVH series is compatible with many piping arrangements through a wide assortment […]
Can you pneumatically, linearly control a hydraulic valve?
As far as positioning of the valve, hydraulic valves already exist in various ways of actuation. For example, you take a big DO8 valve which is a very large spool it’s an industrial valve. You would not make a DO8 with a lever because of what’s called flow forces. The pressure that is acting on […]
