Cartridge Check Valves

Cartridge check valves (also called non-return valves) are designed for simple installation and offer outstanding performance inside mating housing. They are valves that only allow water to flow in one direction and prevent backflow. XHnotion cartridge check valves are not only for water, but also for air now. Applications include faucets, showers, valves, and heating systems for residential or commercial installations, as well as pumps. All the models are 100% tested during production for drip tight operation. Maximum temperature and pressure rating is for most models 200°F (90°C)/230psi. The average cracking (opening) pressure of most valves is between 0.25 and 0.33 psi. **Working Principles** - **In static conditions (no flow):** The check valve is normally closed. The spring tension forces the plunger into its seat keeping the check valve closed. - **In dynamic conditions (flow):** The water pressure exceeds the spring tension. The plunger is lifted off its seat allowing water to flow through the valve. - **In backflow conditions (reversed flow):** If the pressure downstream of the valve increases or if the system pressure upstream decreases, causing the flow to reverse, the spring-loaded plunger closes and prevents backflow. **Features and Benefits** - Zero leak at low and high pressure and temperature. - Generous flow structure promises the lowest headloss. - Compact, easy installation, 8mm-50mm diameter to meet all the system. - No thread connection to avoid potential leakage.

Di-Benzoyl Peroxide 75%

BPO75% is a free flowing granular form of water damped diacyl peroxide, used as initiator of polymerization in styrene,

acrylic resins; and curing agent for unsaturated resin and elastomers.

Melt point:103-106°C(decompose)slightly soluble in water,ethanol,soluble in aether, acetone, chloroform and benzene.

Benzoyl peroxide, also known as Dibenzoyl peroxide, commonly known as Initiator BPO,It is a strong oxidant, used as a monomer polymerization initiator for polyvinyl chloride, unsaturated polyesters, polyacrylates, etc., as a crosslinking agent for polyethylene, and as a rubber vulcanizing agent.
Benzoyl peroxide is an oxidizer, which is principally used as in the production of polymers.
As a bleach, it has been used as a medication and a water disinfectant.In specialized contexts, the name may be abbreviated as BPO.
As a medication, benzoyl peroxide is mostly used to treat acne, either alone or in combination with other treatments.Some versions are sold mixed with antibiotics such as clindamycin. t is also used in dentistry for teeth whitening.
Benzoyl peroxide is also used in the plastics industry and for bleaching flour, hair, and textiles.It is also used to remove stubborn stains from dolls and other plastic toys, although some users have claimed that the product has unwanted long-term effects of discolouring the item.
