DN1600 Split Type Special Vertical Hydraulic Test Bench for Butterfly Valves

This DN1600 Split Type Special Vertical Hydraulic Test Bench for Butterfly Valves is applicable to strength and sealing performance tests of flange-connected and wafer-connected butterfly valves. It adopts synchronous moving jaws to realize synchronous clamping; two structural forms (single-station and multi-station) are optional when placing orders. 

Customers can independently select test media: clean water, compressed air or diesel oil. The machine is standard equipped with low-pressure water pump, high-pressure booster pump and circulating water tank. Optional auxiliary modules include intelligent test data management system, hydraulic air cooling system and automatic hydraulic unloading system. The test caliber and maximum test pressure can be customized according to customer actual production requirements, fully complying with GB/T13927-2022 and API 598 industrial valve pressure testing standards.

Fixed basic parameters sourced from your picture materials: Applicable caliber range: DN1000 ~ DN1600 Overall dimension: 2500×2500×1600mm Total machine weight: 15 tons Rated power: 15 KW

Seven Core Differentiated Advantages

1.Split Vertical Integrated Structure, Suitable for Super Large Caliber Heavy Butterfly Valves The core design advantage of DN1600 Split Type Special Vertical Hydraulic Test Bench for Butterfly Valves: Split split-body layout + vertical clamping structure, specially developed for DN1000-DN1600 extra large pipeline butterfly valves. Vertical clamping effectively avoids bending deformation of large-diameter thick and heavy valve bodies caused by horizontal placement, clamping is more stable and centering accuracy is higher.

2.Four-jaw Synchronous Hydraulic Clamping Mechanism Adopts multi-jaw synchronous moving transmission design, all clamping jaws advance and retreat at completely consistent speed, the valve is always kept in the central position during clamping, uniform stress around the flange, no unilateral deflection, thoroughly solve the sealing leakage problem easily occurring during pressure test of large butterfly valves.

3.Single-station / Multi-station Dual Optional Layout Two configurations can be selected according to production capacity demand: single workstation for small-batch intermittent inspection; multi-station layout for assembly line mass continuous detection, flexible switching to adapt to different production scheduling needs of manufacturers.

4.Three Optional Test Media + Closed-loop Circulation Water System Supports water, air, diesel three test media to meet the inspection requirements of different working conditions; built-in large-capacity circulating water tank collects test wastewater for repeated recycling, saves water consumption and keeps the workshop environment clean.

5.Low-pressure Water Filling + High-pressure Stepped Boost Dual Pump System Low-pressure pump quickly fills the valve cavity and exhausts internal air; high-pressure pump performs graded pressure rise and long-time constant pressure holding. PLC constant pressure control automatically compensates pressure loss, pressure control precision meets the multi-stage pressure holding requirements of API 598 standard.

6.15-ton Super Heavy-duty Rigid Frame With Stress Relief Treatment The whole frame is integrally welded with extra thick steel plate and treated by stress relief annealing, with a total bearing capacity of 15 tons. Long-term continuous heavy-load operation has no frame shaking, twisting or deformation, and the clamping benchmark is permanently stable.

7.Modular Optional Intelligent Upgrading Function Suite Customers can freely select three optional systems: intelligent data recording management system, hydraulic air cooling oil temperature reduction system, automatic pressure relief unloading system after test completion, which can be added and upgraded at any time in the later stage.

FAQ & Official Purchase Guidance

Frequently Asked Questions

Q1: What is the advantage of vertical split structure compared with horizontal test bench for large butterfly valves? 

A1: Large-caliber butterfly valves are heavy and bulky; horizontal placement is prone to bending deformation under self-weight, leading to sealing deviation. Vertical clamping ensures the valve is vertically stressed uniformly, centering is accurate, and test data is more authentic.

Q2: Can single station be changed to multi-station later? 

A2: The equipment framework reserves expansion interface, multi-station transformation can be carried out according to later production capacity growth demand.

Q3: Can data recording, air cooling and automatic unloading functions be installed after delivery? 

A3: All optional modular functions support post-installation and upgrading.

Q4: Can CE certification be processed for overseas export business? 

A4: We can complete full EU CE industrial machinery safety transformation, configure multi-language touch panel and 415V export voltage, issue official CE certificates for overseas customs clearance and project acceptance audit.

Q5: What is the standard production delivery cycle? 

A5: Standard single-station configuration: 40 working days; customized multi-station intelligent upgraded version: 48 working days.
