Product details

NSV Pneumatic Actuator Butterfly Valve which can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of a ball valve, which allows for quick shut off. Butterfly valves are generally favored because they are lower in cost to other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the center of the pipe, passing through the disc is a rod connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow.

STRUCTURAL FEATURES

THE LAMINATED DISC SEAL

Torque seating during closing of the valve provides uniform forces around the entire circumference of the valve seat.The resilient seal flexes and energizes,assuming the shape of the seat.The compression forces equally distributed around the perimeter provide a tight bi-directional shut off.The resiliency of the seal allows the valve body and disc to contact or expand,without the risk of jamming due to temperature fluctuations.

NSV provides an extra rigid retaining ring with bolting,designed in response to ASME stree calculations.

1) Seat is hardfaced with Stellite as standard.

2) The gasket is spiral wound SS/Graphite for zero leakage.

The torqseal’s advanced design features 3-way eccentricity and unique elliptical seat geometry ensuring compressive sealing around the entire seat and a “tight”,bubble free valve.

Raised,conical seat prevents solid build-up from interfering with the seal.Seat is hardfaced with Stellite to meet severe service(in lieu of soft SS316 hardfacing).

IDENTIFICATION OF THE VALVES BEFORE INSTALL ON PIPELINE

1.Each valve has a stainless steel nameplate fixed to the body.the nameplate is marked with details such as valve size,rating,material of construction and series number of the valve,a typical nameplate is shown bellow:

2.Tag number will also be attached to the valve if requested at the time of order.

FAQ

1. Q: What’s the valves warranty?
A: Our valves warranty period should be 18 months from the date of shipment or 12 months after installation, whichever occurs first.

2. Q:What’s the packing for shipping?

A:Its carton for small valves(sample) and plywood case(don’t to fumigate).

3.Q:Is there have MOQ?

A：No.we can accept 1set,but there have additional cost $150.00(process of export) if the order value within $2000.00.
