Ivalve Tech. (Tongling) Co.,Ltd. products

Threaded gate valve, for drinking water connections, irrigation, hydraulic and civil works, etc. It has minimal pressure drop and is 100% watertight, full bore and removable when installed under load.

This kind of gate valves are designed well in every detail. The wedge is fully vulcanized with approved EPDM rubber . It features an outstanding durability due to the ability of the rubber to regain its original shape, the double bonding vulcanization process and the sturdy wedge design. The high strength stem and the thorough corrosion protection safeguard the unmatched reliability. The outside diameters of the spigots are the same as those of cast iron pipes; (other sizes on request).

Dual plate wafer check valves, have two springs loaded half-moon shaped discs that rotate around their shaft. They are designed to automatically prevent back-flow in systems where it is desirable to permit flow in one direction and prevent flow in the opposite direction.

Silent check valves, also known as non-slam check valves and spring-assisted check valves reduce or eliminate water hammer and its effects. Water hammer refers to the high-pressure shock waves that occur when the flow of fluid abruptly stops (due to pump shut down or a valve disc quickly closing) in a piping system. When water hammer occurs, the resulting flow reversal places severe stress on the pipe, endangering its structural integrity, and opening it to potential rupture and damage.

Ball check valves contain a ball that sits on the seat, which has only one through-hole. The ball has a slightly larger diameter than that of the through-hole (seat). When the pressure behind the seat exceeds that above the ball, liquid is allowed to flow through the valve.

Hydraulically operated, pilot-controlled, pressure relief valve designed to maintain constant upstream pressure within close limits. This valve can be used for pressure relief, pressure sustaining, back pressure functions in a by-pass system. In operation, the valve is actuated by line pressure through a pilot control system, opening fast to maintain steady line pressure but closing gradually to prevent surges. Operation is completely automatic and pressure settings may be easily changed by adjusting screw on top of the pilot.

Our pressure reducing valve is a hydraulically driven, pilot valve-controlled control valve. Automatically reduces a higher inlet pressure to a steady lower downstream pressure, regardless of changing flow rate and/or varying inlet pressure. This valve is an accurate, pilot-operated regulator capable of holding downstream pressure to a pre-determined limit. No matter how the flow rate or pressure before the valve fluctuates and changes, the valve can reduce the pre-valve high pressure to the post-valve low pressure and keep it stable, even if the valve does not have user water. It can keep the outlet pressure stable.

Air release valves are offered in single and double chamber configuration and used for filling / emptying the water in addition to the removal of accumulated air in the pipeline. Float material is non-corrodible, and the complete valves is compatible for potable water use. Designed to vent out the air that collects at high points in a pipeline. This valve continuously eliminates air from the system by releasing small quantities of air before large air pockets can occur.

The center line of the disc rotation is horizontally and vertically offset from the body seat. This high-performance designeliminates“seat set” compression while the valve is in the open position. Compression on the seal is released after only a few degrees of opening which reduces friction and wear. This makes the valve ideal for modulation or in the open position for extended periods of time.

Flanged Centric type Butterfly Valve is usually used water supply and drainage, gas pipeline for the temperature ≤80?, nominal pressure ≤ 1.6Mpa to regulate the flow and cut off the fluid role.
