Today, let’s take a look at the classification of self-sealing forged steel valves.
Forged steel valves can be classified into forged steel check valves, forged steel gate valves, forged steel ball valves, forged steel globe valves, forged steel check valves, self-sealing gate valves, self-sealing globe valves, self-sealing check valves, forged steel needles. Valve, forged steel insulation valve, forged steel bellows valve, etc.
Forged steel gate valves often ignore pressure problems. In the grease injection operation, the grease-loaded regular semi-free float-type steam trap has a peak-to-valley change. The pressure is too low, the seal leaks or the safety valve fails, the pressure is too high, the grease port valve manufacturer is clogged, the seal grease hardens or the seal ring and the valve ball and the valve plate are locked. Usually, when the grease pressure is too low, the injected grease flows into the bottom of the valve cavity, which usually occurs in a small gate valve. The pressure of the grease flow control valve is too high. On the one hand, the grease valve is inspected and the grease nozzle is inspected. If the grease remote control float valve hole is blocked, the spring seal is replaced with a wrench. The other plunger valve is a lipid. For hardening, use a cleaning solution, repeatedly soften the failed sealing grease, and inject a new grease to replace it. In addition, the sealing type and sealing material also affect the grease filling pressure. Different sealing forms have different grease filling pressures. Generally, the hard sealing grease pressure is higher than the soft sealing.
Forged steel globe valves pay attention to the problem of the valve in the switch position. The ball valve is normally in the open position during maintenance and maintenance. In special cases, the maintenance is turned off. Other valves cannot be discussed in terms of opening. Forged steel shut-off valves must be closed during maintenance to ensure that the grease fills the seal groove along the seal. If it is open, the seal grease will fall directly into the runner or valve cavity, resulting in waste. When the valve is greased, the problem of grease injection is often ignored. The pressure, grease injection amount and switch position are normal during the grease filling operation. However, in order to ensure the grease filling effect of the valve, it is sometimes necessary to open or close the valve to check the lubrication effect and confirm that the valve ball or the surface of the valve is evenly lubricated.
I believe that through the above introduction, everyone has already understood the classification of self-sealing forged steel valves.

The Foot Valve is composed of valve body, disc, cover, bushing, sealing ring and other parts. See the water from the water source in the figure below. Under the pressure of the fluid, the disc opens water. When the pressure in the outlet pipe is stopped, the disc closes quickly. The liquid will not pour back to the water source. It plays the role of unimpeded pumping and saving water and energy loss.
The Foot Valve or Bottom Valve, which is actually a kind of check valve and plays a role in preventing water backflow.
Foot Valve can be divided into plastic Foot Valve and metal Foot Valve according to the material, and can also be divided into ordinary Foot Valve and backwashing water Foot Valve.
Foot Valve are mainly used in mechanical equipment for slurry treatment such as pumps. Usually,Foot Valve are installed at the bottom of underwater suction pipes of pumps to prevent slurry backflow.
Foot valve is equipped with multiple inlets on the valve cover and screen mesh to reduce the impurity inflow and the blockage probability of the Foot Valve. Although the Foot Valve is equipped with anti-clogging screen mesh, the bottom valve is generally suitable for cleaning media. The Foot Valve is not suitable for medium with excessive viscosity and granularity.

Stainless steel Foot valves are widely used in water treatment equipment, chemical equipment, petrochemical equipment, petroleum equipment, papermaking equipment, mining equipment, power equipment, liquefied gas equipment, food equipment, pharmaceutical equipment, water supply and drainage equipment.
Stainless steel material AISI 304 (CF8). Seat 304 material, gasket PTFE. With manual system to empty. Max. working pressure 16 bar.
The stainless steel foot valve is an energy-saving valve that is typically installed at the bottom of the pump’s underwater suction tube. Restrict the return of liquid from the water pump tube to the water source, and it can only function as an inaccessible. There are a lot of water inlets and ribs on the bonnet, which is not easy to block, and is mainly used in the pumping pipeline. The role of waterways and supports. The calibers are single-lobed, double-lobed, and multi-lobed. Under the pressure of the fluid, the valve flap opens the water. When the pressure in the outlet pipe is quickly closed after the stop, the liquid will not be returned to the water source, which will serve as a smooth pumping and save water energy loss.
Understand the characteristics and operation mode of the forged steel Y-typeStrainer. The pipe with the forged steel Y-type Strainer can be divided into intermittent operation and continuous operation during operation. In the case of intermittent operation, a shut-off valve is provided before and after the forged steel Strainer to clean the filter. For continuous operation, two sets of filters in parallel are required for the permanent filter, and the shut-off valves are respectively arranged before and after the filter.
Characteristics of forged steel Y-type Strainer:
1, full diameter or reduced diameter.
2. The socket end is in accordance with ASME B16.11.
3, bolted, wound gasket sealed bonnet.
4. The threaded end (NPT) conforms to ANSI/ASME B1.20.1.
5, can be equipped with discharge blockage, replaceable filter.

1. The integral flange forged steel valve is mainly applied to the pipelines of various systems of the thermal power station, cutting or connecting the pipeline medium. Applicable medium: non-corrosive medium such as water and steam. Compared with other valve products, the integral flange forged steel valve is characterized by high temperature and high pressure and unique self-sealing design. The higher the pressure, the more reliable the seal. Due to the special technical characteristics and working conditions, the products also form features that cannot be replaced by other products.
2. Introduce the processing method of integral flange forging steel valve body forging, which is to take the blanking, pre-forging, final forging and trimming in turn. The characteristics are pre-forged initial blank after blanking, which is to forge the outer diameter of the material. It is larger than the outer diameter of the flange on both sides of the valve body, and then the middle portion is flattened, and the thickness of the middle flattening is larger than the outer diameter of the flange in the valve body, and the initial shape is formed to be longer than the length of the flange on both sides of the valve body. The blank (referred to as a blank) is placed in the upper and lower molds for the final forging of the unidirectional die forging after the blanking, and the trimming is performed after the final forging. Further, for small-diameter flange valves, because the flanges on both sides are close to the middle flange, in order to ensure that the unidirectional die forging process is sufficient while simultaneously discharging the waste to the two adjacent flange positions, the edge flange and There is a gap between the upper and lower mold edges between the middle flanges.
