As a trusted valve manufacturer China, we are also an OEM valve manufacturer and professional custom valve manufacturer. Below is our H44H-16P swing check valve with hydraulic actuator.

Model: H44H-16P (adjustable according to working conditions)Nominal Size: DN200Pressure Class: PN16End Connection: RF Raised Face FlangeBody Material: CF8 (304 Stainless Steel)Disc & Shaft Material: 304 Stainless SteelSeat Type: Metal Hard SealStructure: Swing Check Valve with hydraulic actuatorDesign Standard: GB/T 13927, API 6DTest Standard: API 598

Swing type structure with smooth flow passage and low flow resistance, suitable for medium transportation in large-diameter pipelines. Equipped with hydraulic actuator to assist opening and closing actively and suppress water hammer.

CF8 (304 stainless steel) body resists weak acid, weak alkali, moisture and corrosive media, widely used in chemical industry, water treatment, energy, pump station and other industrial pipelines.

Metal hard sealing structure features high temperature resistance and erosion resistance, applicable for high-temperature media with tiny solid particles, providing long-term stable tightness.

Matching hydraulic cylinder enables controllable valve closing, effectively restraining pipeline water hammer and protecting downstream equipment such as pumps and pipelines.

Swing disc operates smoothly with small opening/closing impact. Standard RF flanged ends match standard industrial pipeline flanges, suitable for horizontal pipeline installation.

High-rigidity integral structure, bolted bonnet design facilitates internal maintenance and replacement of sealing components.

100% hydrostatic shell strength test & tightness test before delivery; PT/UT NDT inspection for castings available.
