    DESCRIPTION

    What is a non-rising stem gate valve?

    Non-rising stem gate valve is one type of gate valve with flexible wedge as its on-off disc, which moving direction is perpendicular with flow. Non-Rising Stem means outside stem, also referred to as the rotary stem gate valve or blind stem wedge gate valve. In an NRS valve, the stem will turn to open and close the gate, but the stem does not move up or down as it turns. Gate valve can be only full open or full close. They are widely used in series of industries, especially in water supply projects, public works, water treatment plant, fire fighting, etc. Prosper Flow can manufacture resilient seated gate valve according to the standard of DIN3202 F4/F5/BS5163 with sizes of 2″~32″ (DN50~800mm).

    How does a di ball check valve work?

    A ball check valve has an internal conically tapered shape for the sealing seat and a ball. ... It forces the ball off of the sealing seat and allows media to flow through. When there is back pressure, it moves the ball back to the seat seal (assisted by the spring if designed with one).

    Ball check valve price

    Since the size and model of ball check valve are different, we also choose materials according to the ball check valve price. Therefore, we cannot make an accurate quotation for you. If you need ball check valve price, please contact us with your parameters!

  • PN10 / PN16 DI Lug Type Butterfly Valve

    DESCRIPTION

    Wafer type butterfly valve is one type of central lined butterfly valve, which is one normal type of butterfly valve in need of big quantity. It is mounted between two matching flanges of the piping with bolts & nuts. According to actual piping conditions, wafer type butterfly valve can be manufactured according to different flanges standards, such as , EN1092, AS2129, DIN2501, BS4504, JIS10K. Wafer butterfly valve can be mounted on the piping end as exhaust valve. Prosper Flow can produce the wafer butterfly valve rubber lined in accordance with EN593, API609 and AMSE .lug butterly valve

    What is the difference between lug and wafer butterfly valves?

    The difference between a Wafer and Lug type Butterfly valve is only the mounting scheme [1] and [2]. ... Wafer type valves don't have attachment lugs, though them may have alignment lugs. They are sandwiched between the flanges on the ends two lengths of pipe.

    What is the function of a butterfly valve?

    The main function of these valves is to control the flow of liquids through a section of pipe. Butterfly valves are mainly used in waste treatment systems. They are extremely durable and need minimal maintenance. Butterfly valves operate like other quarter turn valves.

    What is a lug style butterfly valve?

    Lug-style valves have threaded inserts at both sides of the valve body. This allows them to be installed into a system using two sets of bolts and no nuts. The valve is installed between two flanges using a separate set of bolts for each flange.
