Our 30ч39р valves use a EPDM wedge design,making them an ideal choice for water supply and heating systems. Both the valve body and bonnet are precision-cast from high-quality ductile iron in our own foundry, ensuring sturdy and durable products right from the start. For coating, we use an epoxy resin coating, which not only provides outstanding corrosion resistance […]
Electric Knife Gate ValvesProduct Overview and Operating Instructions: The actuator section of this product utilizes a multi-turn electric device to drive and control the opening and closing of the valve. (The electric actuator requires connection to a separate control box for operation.) Operators can control the valve remotely from a control room, operate it manually
There are many kinds of check valves, including swing check valves, double-lobe clamp check valves, silence check valves, slow-closing check valves, double-lobe clamp check valves and so on. In the previous articles, we introduced the swing check valve, the lifting check valve, and the double lobe clamp check valve, in this article we will introduce in
Cast iron metal sealed gate valves are the core components of industrial pipelines, and their quality and compliance are essential. Choosing to have EAC certification is a prerequisite for avoiding risks and ensuring operations. 一、Choosing a cast iron metal sealed gate valve with EAC certification is the dual bottom line of compliance access and safety
The silent check valve is also known as the nozzle-type check valve and the axial-flow check valve. It consists of the valve body, valve seat, valve plate, valve shaft, spring, and guide fluid. Both the silent check valve and the sound-absorbing check valve have the effect of reducing noise, but the sound-absorbing check valve has
What problems can be solved by installing an exhaust valve in the pipeline system After turning on the pump, the water flow in the pipeline is still intermittent and even accompanied by abnormal noise, the problem may be in the air in the pipeline, if it is not discharged in time, it will occupy the
On the basis of strictly following the standard structural length of the EN558-14 series, this DIN F4 gate valve has been completely optimized, taking into account the structural stability and durability, and adapting to the needs of a variety of industrial scenarios. The valve body and the handwheel are designed with a unified material, which
Relief valves and pressure reducing valves look very similar in appearance and have similar names, both sounding like they are dealing with pipeline pressure. However, their functions are completely different. If they are confused, it could lead to serious mistakes. A pressure reducing valve is responsible for converting high pressure to low pressure. If the
The safety valve should be manually vented regularly to prevent the valve core from sticking. The operation should be slow in lifting and quick in releasing. Safety valves are typically installed vertically in gas-phase pipelines, with the inlet being short and straight, and the diameter larger than the cross-sectional area. Generally, the outlet pipe for

Parallel Double-Disc Gate Valve : The two sealing faces of the gate are parallel to each other; this type is subdivided into two categories: the *self-sealing type* and the *spreading type*. The self-sealing parallel double-gate valve relies on the pressure of the medium to push the gate against the sealing face of the outlet-side valve
There is a set of fixed valve combinations before and after the water pump. A shut-off valve and a filter are installed before the water pump. The shut-off valve is responsible for cutting off the system during maintenance, and the strainer is responsible for filtering the medium in advance to prevent impurities from clogging the water
In fluid control scenarios such as industrial water supply and drainage, oil and gas, and chemical engineering, gate valves are the core components for controlling the on-off of pipelines. Traditional manual gate valves, under large-diameter and high-pressure working conditions, require multiple people to repeatedly turn the valve stem to open and close, which takes dozens
Because the sealing rings of soft-seal butterfly valves are mostly made of rubber or PTFE, excessive pressure can damage them. Therefore, if the actual operating pressure is low, the shell pressure test can be reduced, and only the seal pressure test needs to be performed. Shell pressure testing increases equipment and time costs. Therefore, for
