Features: Reliable and durable. Simple inner structure, nice workmanship. Apply to: Hydraulic instability, water circulation too fast, water purifiers, photo voltaic energy, gas and faucet. operating precept can be smoothly understood since the front pressure and outlet strain = spring force, through the management closure motion contained in the opening of the dimensions to administer the strain on the outlet, the water during the opening, closure and fluid resistance is small, the strain loss is small, the hole strain is greater, and outlet stress is small.
