• Silent check valve is used as protection against reverse flow when power failure in areas where noise pollution or water hammering is a critical issue. It can provide not only quiet performance but also low head loss
• High strength ductile iron body used for durability and less weight.
• Advanced dynamic design of single body with diffuser provides streamline flow and assures lower head loss.
• One of the lowest head loss check valve, big save in pumping power cost, valve disc with shorter stroker and spring reverse faster than most of check valve.
• Coated with powder epoxy both inside & outside for corrosion resistance.
• Bronze bushing reduce wearing problem during operation.
• Hydrodynamic design with spring ensures non slamming and water hammerless.
• Stainless steel spring hidden in the diffuser under protection while valve in operation.
• Disc will positively close before reverse flow, and maximize the closing speed up to 0.2 Sec.
• Installation can be vertical/horizontal/inclined.
• Comply with EN 558-1, ISO 5752 and EN 1092-2, ISO 7005-2 flange dimension.

Feature of check valve:
A check valve, clack valve, non-return valve or one-way valve is a valve that normally allows fluid to flow through
it in only on direction.
Check valves are two-port valves, meanting they have two openings in the body, one for fluid to enter and the
other for luid to leave, there are various types of check valve used in a wide variety of applications, check valve are
often part of common houshold items, They work actuomactically and most are not controlled by a person or any
We also make the electric actuator:
FOLS electric valve actuator has the multi-funtion such as: ON/Off function,regulating functhion
(whatever you can adjust the dis of butterfly valve), it depens on your technical for butterfly valve.
We have different kinds of butterfly valves, each adapted for different pressures and different usage. The zero offset
butterfly valve, double offset butterfly valve, the triple offset butterfly valve. also has different connect type: flange conn-
ection butterfly valve, wafer-style butterfly valve, At last: Concentric butterfly valves, Doubly-eccentric butterfly valves(
double-offset butterfly valve) Triply-eccentric butterfly valves ( triple-offset butterfly valves), We waiting for your selectin.
Pindly noted: all this butterfly valves can assemble our electric actuators

Why Choose US
Our factory is specialized in valves' production. As one of the biggest and most professional manufacturer and exporter majored in valves, we assure that we can provide our products with cheapest price, good quality and best service. If you like, welcome to our factory and have a look!
We test leakage of each roll before braiding, then we cut 300mm and crimp it to test
burst pressure after brading.
We use CNC Lathes Machine for end fittings production. Machine system, knife and inspection
tools are all imported from Japan.
We use Techmaflex Crimping Machine which is imported from France. This machine has
accurate and stable performance for crimping because it is produced for PTFE hose crimping only.
