"This is an impressive resume and adding to it is the capability of the valve to perform effectively with extreme pressures"

Various names are given to a mechanical valve that permits the flow of fluids, liquid or gas in a single direction. These include a check valve, non-return valve or a one-way valve. The manual operated rubber valve has a basic assembly of a body, with a pipe connection and some elements for sealing functions, usually operated by an actuator.

To complement the valve, there are several accessories that can be used, for example positioners and pressure regulators, among others. A ‘check valve’ could be simply described as a two-port component- it has two openings in its casing, one being for fluid to enter and the other for it to exit. Manual rubber valves are utilized in many and varied applications and can be found as a part of common household equipment.

In industries involving fibrous and corrosive applications, there is an increasing need for manual operated squeeze valves. The valve type is highly suitable for this demanding application due to its ability to serve as a blocking method and ease of closing. An ongoing benefit of this valve to users is its potential for operation by a hand-wheel, or automatic means. The ever-increasing demand for manual squeeze valves is created by industrial processing plants seeking to improve and find more affective means of controlling production and labor related costs.

Various industries have specialized applications and in order to satisfy this demand, the all important inner sleeve of the valve is manufactured in a variety of elastomer qualities. The control squeeze valves are therefore extremely versatile in applications that require specific operating temperatures. There are a myriad of substances that are subject to a control hose valve, from the thinnest of gases to radio active materials, this well recognized valve type is used in continuous industrial service. Other applications include the processing of high corrosive chemicals or extremely hot steam and abrasive slurries. Adding to their capabilities in the process of difficult materials is the ability of the manual operated hose valve to operate in extreme variations of temperature.

This is an impressive resume and adding to it is the capability of the valve to perform effectively with extreme pressures. These can be from a high vacuum to a pressure of thousands of pounds per square inch. Although this component is generally perceived as a common household item, the manual hose valve is in fact, a highly regarded and important part of many industrial processes.

Within the oil and gas industries, industrial fittings and components are utilized in various aspects on offshore platforms. Control tube valves are utilized in industries of this nature in applications such as sub-sea control systems and offshore production including pipelines. As this type of operation requires strict norms and measures, any equipment or component must be manufactured to an extremely high quality and designed for reliable performance with minimum downtime. Manual tube valves have an excellent resistance to chemical and atmospheric agents and have the capacity to perform in adverse weather conditions with a low maintenance factor.

With the valve fully opened, the fluid flow is in a direct line and the collar of the tube replaces the need for a gasket. At the same time, it assists in the maintaining of a positive control over the flow of the fluid. The construction of a manual operated tube valve consists of a casing, flanged or screw-type ends and a tube, referred to as an insert or liner. The closing of the valve whether it is screw type or flange, is either manually or by air pressure. A sleeve valve is designed to operate within its flow range without damaging cavitations for the specified conditions. A control sleeve valve application will be enabled by the incorporation within the design of multiple tapered outlets on the internal sleeve. The outlets will be arranged in a formation whereby water streams will be directed to meet at the centre of a downstream discharge pipe.

A manual operated sleeve valve shall have the capacity of regulating a flow by a linear motion, which exposes the number of outlets needed to achieve a correct rate of flow. The casing of the valve is flanged at both ends and in a manual capacity, is usually regulated with a handle or wheel type device. A benefit for users of a manual sleeve valve is the simplicity of its design, which factor contributes to minimum downtime and low maintenance costs. The only part of the valve subject to wear is the inner sleeve. Aside from this component, the valve does not have any mechanical parts and the use of an actuator is not required. The valve and provides a clear, true bore.

In many applications, there is a requirement for a material or fluid flow to be regulated or throttled at a certain point between full flow and a minimum rate. Control pinch valves achieve this by the introduction of flow resistance or the by-passing of a flow, created by a change of direction.

A beneficial operating feature of a manual pinch valve is the ability to connect directly to a closing mechanism and ensure a forced opening. This is achieved by what are referred to as ‘opening tabs’. The watering of a garden or washing of an automobile, follow the principle operation of a manually operated pinch valve simply by the compressing of the hose between the fingers thus, shutting off the flow of material.
