Control ValveMore >>
Control valves are valves used to control conditions such as flow, pressure, temperature, and liquid level by fully or partially opening or closing in response to signals received from controllers that compare a "setpoint" to a "process variable" whose value is provided by sensors that monitor changes in such conditions.
Balancing ValveMore >>
The balancing valve is a special function valve. The valve itself has no special features. It only uses all the functions and fields. In some industries, due to the large pressure difference or flow difference in the various parts of the pipe or container due to the medium (variable flowable substances), in order to reduce or balance the difference, between the corresponding pipes or containers Install a valve to adjust the relative balance of the pressure on both sides, or to achieve a balance of flow by means of a split flow, the valve is called a balance valve.
Gate ValveMore >>
The gate valve is a shutter of the opening and closing member. The direction of movement of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully open and fully closed, and cannot be adjusted and throttled. The gate valve is sealed by the contact between the valve seat and the gate. Usually, the sealing surface will be welded with metal material to increase wear resistance, such as surfacing 1Cr13, STL6, stainless steel, and the like. The gate has a rigid gate and an elastic gate. According to the gate, the gate valve is divided into a rigid gate valve and a flexible gate valve.
Butterfly ValveMore >>
The butterfly valve, also known as the flap valve, is a simple regulating valve. The butterfly valve that can be used for the switching control of the low-pressure pipeline medium means that the closing member (valve or disc) is a disc that rotates around the valve shaft to achieve opening and closing. a kind of valve.
Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media. Mainly cut and throttle on the pipeline. The butterfly valve opening and closing member is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjusting.Check ValveMore >>
A check valve is a valve in which the opening and closing member is a circular valve flap and acts on its own weight and medium pressure to block the reverse flow of the medium. It is an automatic valve, also known as a check valve, check valve, return valve or isolation valve. The flap motion mode is divided into lift type and swing type. The lift check valve is similar in construction to the shut-off valve and lacks only the valve stem that drives the flap. The medium flows in from the inlet end (lower side) and flows out from the outlet end (upper side). When the inlet pressure is greater than the sum of the valve disc weight and its flow resistance, the valve is opened. Conversely, the valve closes when the media is reversed. The swing check valve has a valve flap that is inclined and rotatable about the shaft, and operates in a similar manner to the lift check valve. Check valves are often used as bottom valves for pumping devices to prevent backflow of water. The combination of the stop valve and the shut-off valve provides a safe isolation. The disadvantage is that the resistance is large and the sealing is poor when closed.
Air ValveMore >>
A gas valve is a component of a compressor that controls the flow of gas into and out of a cylinder. Mainly composed of valve seat, valve plate, spring and lift limiter. The lift height or closure between the valve plate and the valve seat determines the size and sealing of the gas passage. The spring is mainly used to push the valve to close, and it can also reduce the impact of the valve on the lift limiter when it is opened. The lift limiter can limit the lift of the valve plate and can bear the spring; the opening and closing of the valve plate is controlled by the gas pressure difference between the cylinder and the outside and the spring force, so no other drive mechanism is required, so it is called an automatic valve.
Strainer & Dirt SeparatorMore >>
A filter is an indispensable device on the conveying medium pipeline. It is usually installed in the pressure reducing valve, pressure relief valve, fixed water level valve, and the inlet device of other equipment of the square filter. The filter consists of a cylinder, a stainless steel strainer, a draining section, a transmission and an electrical control section. After the water to be treated passes through the filter cartridge of the filter screen, the impurities are blocked. When the cleaning is required, the detachable filter cartridge can be taken out and re-loaded after the treatment, so that the maintenance is extremely convenient.
